Chelsea Handler and Nick Cannon are feuding over Twitter, and it's gotten ugly.

It all started when Chelsea found out Nick was going on tour.

"I just heard nick cannon is starting a comedy tour. Who's going to do the comedy?" she tweeted on Thursday.

"Wow @chelseahandler I actaully used to have respect for you as a comic. But for one artist to diss another in the same art form. #Tasteless," Nick responded. "Soon as I get off stage tonight, I'm going in on @chelseahandler I'm about to be relentless! OFF WITH HER HEAD but right now I got to focus."

"@nickcannon pls drink this before you tweet me again," Chelsea responded with a photo of a grape soda.

After his show, Nick returned to Twitter with a stream of colorful insults about Chelsea's appearance and career (above).

He capped off his rant with a disclaimer and a plug for his show: "Just jokes people, LOL! Well I got to be at my next job in a few hours so I will continue the jokes on my morning show. Tune in @923nowfm," he tweeted.

THIS ONE GOT ME SCREAMIN'! "THE CYPHER" F/KANYE WEST AND THE GOOD MUSIC FAM. YOU GOTTA CHECK IT.

RIHANNA ROLLIN IN IT!

Even though Rihanna had to cancel some shows off her “Last Girl On Earth Tour” because of poor concert sales, she still shoveled in DOUGH.

According to The Smoking Gun Rihanna made a guaranteed $410,000 bucks per show and the right to receive 80% of box office ticket receipts over $565,000.

Justin Bieber makes $300,00 per show, Drake gets $150,00 – but none of them can top Beyonce, though. She demands $1.5 million or more per show on tour.

Lil Wayne Inks Last Rikers Island Letter

“Hello world. Time is ticking and I’m counting every second. Because of my new limitations, this unfortunately has to be my last letter. I don’t think people truly understand how much their thoughts and well wishes have helped me through this time in my life. Not everyone is as lucky as I am and it humbles me daily. You would be amazed what positivity can do in a negative environment. I’m going to miss reading about your lives. I’m going to miss looking at the pictures. They were the highlight of my days aside from speaking with my kids. Don’t stress over this in 27 days, the ride starts again.”

JUSTIN TIMBERLAKE & JIMMY FALLON NAIL THIS ISH..."THE EVOLUTION OF RAP". CHECK IT:

My favorite clip of the week has to be from Jimmy Fallon on Late Night. Him, Justin Timberlake and The Roots crushed an awesome medley of hip hop songs through the ages.

In case Justin Timberlake's ability to sing, dance and act ridiculously well didn't give him enough street cred, his recent appearance on 'Late Night with Jimmy Fallon' sealed the deal.Timberlake stopped by 'Late Night' to promote his role in the much anticipated, 'The Social Network.' Gushing over the talent of house band, The Roots, launched Timberlake and Fallon into a full blown medley of rap classics from Sugarhill Gang's "Rapper's Delight" to Jay-Z's "Empire State of Mind," and everything in between.If Timberlake's rapping chops aren't enough for you, Fallon's attempt at the Soulja Boy 'crank that' dance certainly will be. Watch the hilarious video after the jump!

50 CENT HOOKIN UP WIT CHELSEA HANDLER?...

According to TMZ, he is! Chelsea even gushed about it on her show a couple weeks back. Saying how he sent her bunches and bunches of flowers. 50 Cent has been trying to bag Chealsea Handler for a while. And she sure does love her rappers. Sources say they were eating together at a night spot in Atlanta and were later spotted in a hotel lobby together.

What do you think? Is this an upgrade or a landslide from Ciara?

LIL WAYNE THROWN IN DA HOLE.?... SAY IT AINT SO.

Remember when Wayne was caught with an mp3 player and headphones in his cell? Well, now he's reaping the consequences *cue dramatic piano music* and has been banished to solitary confinement.
He was already in a private cell, but now he can have less interaction with other inmates and will be in isolation for 23 hours a day.
His out-of-cell time is now restricted to visits, religious services and one hour of recreational time and his phone privileges are reduced to one personal phone call a week.
FYI: He's on his last 30 days, due to be released on November 4th.SO CLOSE!!

MY NEW VIKES/FAVRE CAP!

I actually grabbed this at a convenience stop in WISCONSIN. LOL!

The cashier was like..."You just gotta rub it in huh?..." "Rub it in real bad there mister!"
I honestly hadn't thought about it till that moment. Oooops!

Twins IRKED by ad overlooking ballpark

MINNEAPOLIS -- Score one for the struggling Minnesota Timberwolves over the playoff-bound Twins.
The Timberwolves have already admitted they probably won't do much winning this season, but they're not short on business acumen: The NBA team has installed a giant billboard on their arena that will be hard to miss for anyone watching the Twins' home playoff games next week.

Artist's rendering via Minnesota TimberwolvesTimberwolves president Chris Wright describes a billboard to be finished in time for the Twins' first playoff game as a good business opportunity.
Renderings provided by the Wolves show the ad space on the outside of Target Center will dominate the view from the third-baseline seats at the Twins' Target Field, as well as from Target Plaza outside the ballpark. It's the same vantage point of downtown Minneapolis that Sports Illustrated recently chose for a cover story on the Twins.
The first advertiser in the spot is Sanford Health, a health care system with operations in six Midwest states. The Twins say the Sanford ad will debut in time for Wednesday's opening game of the divisional series hosted by the AL Central-champion Twins.
The Wolves, who were one of the worst teams in the NBA last season with just 15 wins, wouldn't say how much Sanford Health paid for the ad.
The Twins are fuming, but powerless to stop it.
Team president Dave St. Peter didn't return calls from The Associated Press. But in an interview with MinnPost, an online news site that first reported on the billboard, St. Peter called it "an ambush" and said the size of the billboard was "shocking."
Timberwolves president Chris Wright said he was surprised the Twins are so upset. The Wolves fought and won a court battle with the operator of their arena earlier this year over the right to sell the exterior ad space.
"It was more a question of when we would do it rather than if we would do it," he said by phone from London, where the Wolves were preparing for a preseason game against the Los Angeles Lakers.
He said the Wolves have been happy to see their baseball counterparts so successful in their new stadium, and called it "a shame they would begrudge us" making use of the ad space.

R&B SINGER MARIO ROUGHS UP MOMS?...

R&B singer and former "Dancing with the Stars" contestant Mario has been charged with assaulting his mother at their Baltimore home.
Officers were called to an apartment building in the Fells Point neighborhood early Friday, where police say Shawntia Hardaway told officers her 24-year-old son, Mario Barrett, had pushed her.
According to charging documents, Hardaway said her head still hurt after Barrett pushed her into in a wall in a separate instance on Monday and she feared for her life. Officers found broken glass and a hole in a door in their apartment.
Barrett's attorney, William "Hassan" Murphy III, calls it "an unfortunate incident" between a loving son and a mother who has had drug problems. Barrett, who appeared in an MTV special in which he staged an intervention for his mother, was charged with second-degree assault and released on $50,000 bond.

SKYY SHOWS IT'S SEXIEST SIDE YET?...

Skyy Vodka unveils a sexy outdoor ad campaign for their brand that "depicts a woman clad in red leather tights and high heels getting - um - poked by a vodka bottle," Ad Rants concludes.

The campaign consists of five different executions - "Sexy Legs," "Unzipped," "The Package," "Lip Service" and "Iced Down" - each showcasing a different interpretation of SKYY sexy.

Although Skyy has produced some erotic ads in the past, these new shots seem to have the critics in an uproar. "It's just jamming a bottle in a woman's crotch," branding expert Steven Addis explains. "A great ad uses heart or mind. This one's starting below the waist."
The company disagrees.
"It's about the content of our product," says Maura McGinn, Skyy's marketing director. "We're an adult product consumed mostly in the evening and in flirtatious situations."
Is the ad too HOTT?
