Apparently, Em wasn’t too fond of Mariah’s spoof of him in the “Obsessed” video.

Nick Cannon hit Live With Regis & Kelly on Tuesday to promote the new season of America’s Got Talent – which he will be hosting — premiering on NBC tonight.

America’s Got Talent host Nick Cannon does his best “Bill Cosby” in this video clip from last night’s edition of NBC’s Late Night With Jimmy Fallon.

Nick Cannon has waged a war of words against Eminem after the rapper referenced his wife, Mariah Carey, in a new song.

At the center of the feud is Em’s song “Bagpipes from Baghdad,” — off his upcoming LP, Relapse — which includes lyrics directed toward Mariah, included: “Why did we have to break up/All that I asked for was a glass of punch,” and “I want another crack at ya.”

Eminem also suggests Mariah and Nick should split in the song’s lyrics saying, “Nick, you’ve had your fun/I’ve come to kick you in your sack of junk/Man, I could use a fresh batch of blood.”

On Friday, Nick responded to the track on his official blog, writing:

“I felt sorry for him because he must really be stuck in the past. Not only has his music not evolved, but also homeboy is still obsessed with my wife, the same female that wouldn’t let him get to second base from 8 years ago. What type of grown ass man lies about getting with a chick? Only Slim Lamey! LOL!”

The heated host of America’s Got Talent continued: “As I further examine the track, I hear dude cross the line. He begins to call my wife out of her name! Now as y’all know, I don’t take that type of nonsense lightly,” he wrote. “I know it’s only entertainment and I’m all for freedom of speech. But I’m from the school of thought where if you are tough enough to talk shit, you got to be tough enough to deal with the consequences that come with tough guy shit talking!”

Nick goes on to accuse the White rapper of racial bigotry:

“Maybe I’m going too far, but I thought we got past the days where white men could spew vulgar obscenities at our beautiful queens and get away with it. What’s next? Are we going to let this trash say something horrible about our lovely first lady, Mrs. Michelle Obama? Or would Marshall have talked sideways out of his neck like this about Oprah Winfrey? This act of racist bigotry cannot go unnoticed. Calling my wife a ‘cunt’ and a ‘whore’ is way worse than anything Don Imus could have ever said. So trust, repercussions will be served. Anybody got Al Sharpton’s number?!”

Nick Cannon and Mariah Carey celebrated the one-year wedding anniversary at the Palms Casino Resort in Las Vegas on Thursday night.

“Mariah and Nick are trying anything and everything to conceive,” a spywitness reveals in this week’s edition of The National Enquirer.

“After almost a year of trying the natural way they visited a fertility clinic to help make their baby dream come true. Mariah turns 39 this month, and she really wants to give birth before her 40th birthday.”

Nick Cannon has signed on to emcee NBC’s variety talent competition America’s Got Talent following former host Jerry Springer’s announcement that he won’t be back for the show’s fourth season.

“I’m thrilled to be working with NBC,” Nick says of his new job, adding that those at the network “understand my vision as not only an entertainer but as a creative show producer.” “I look forward to working with the network and their executive team on America’s Got Talent and other shows to come.”

Like much of the music industry, Christina Milian said she was shocked by Mariah Carey and Nick Cannon’s secret wedding in the Bahamas earlier this year.

“I definitely was shocked like everybody else,” Christina Milian, who dated her Love Don’t Cost a Thing costar before he cheated on her in 2005, tells Rap-Up Magazine in its Winter 08/09 issue.

“I was like, ‘Really?’ It just seemed like a weird match. But I was happy for him. I always feel like Nick works hard to get what he wants, whether that be women – that’s how he got me.”

Mariah Carey and Nick Cannon waited until their wedding night to have sex for the first time.

“It’s not that we had no intimacy, we just didn’t have complete intimacy,” Mariah tells Britain’s Daily Mirror.

“And it was, and it still is,” she added.

The 38-year-old songbird dated the young rapper for two months before getting married in the Bahamas last Spring.
