Yesterday, Chris Brown made it official. He said he’d broken up with his girlfriend Karrueche [kaw-ROO-chay] Tran to focus on his career (and have the freedom to hook up with his former girlfriend Rihanna).

This past week, she and Brown went on several dates and made it painfully obvious that the romance had rekindled.

 

Bristol Palin was the target of that suspicious package that was sent to the CBS lot Wednesday.

Bristol was also the target of a threatening letter when she appeared on Dancing With the Stars in 2010.

A Hulk Hogan sex tape has hit the Internet.

It doesn't look like Nicki Minaj and Mariah Carey are going to kiss and make up anytime soon.

Mariah apparently put in a call to her old friend Barbara Walters, who recounted the conversation this morning (Thursday) on The View. Barbara read from her notes, "She said that when Nicki walked off the set, multiple people heard her say, 'If I had a gun I would shoot the bitch.'" Mariah told Walters that she doesn't believe Nicki would actually go to such extreme measures but has beefed up her security just in case.

There was talk of a reconciliation earlier today when Nicki and Mariah managed to attend meetings for Idol without incident. But shortly after that, the Barb Tweeted, "I guess it hurts to have the producers tell you to your face that Nicki is the best judge we've had since Simon. Awww, poor you. Keep them lies comin'." She also accused Mariah of hiding behind powerful friends, writing, "I don't call TMZ and Barbara Walters because I stand on my own two feet. Never needed an army."

The Hollywood Reporter says the whole feud may just be a ratings ploy. The site quotes an unnamed insider saying, "The Mariah-Nicki diva battle is exactly what FOX executives wanted all along. No one's really worried. They know the parts they’re supposed to play.”
