Khloe Kardashian might not be back for more on “The X Factor". The New York Post says she “has not been asked to return as co-host of the high-profile Fox singing competition.” Rumor is FOX is asking Mario Lopez to come back, but not Khloe. A spokesperson for FOX says: “The producers have not yet made the talent decisions for this year.”

Last week, the rumor was John Mayer had popped the question on Valentine's Day to Katy Perry - because she had a beautiful new decoration on her ring finger. Katy flashed a heart-shaped ruby ring to the paparazzi as she left dinner with John that night. No engagement announcement yet, but sources say they ARE planning an intimate wedding - most likely in Katy's hometown of Santa Barbara.

Organizers of the Brit Awards plan to keep Harry Styles away from his ex Taylor Swift during the ceremony tomorrow. They even had their rehearsal times changed to keep them apart before the show. The One Direction dressing room is well hidden - so even if Taylor wanted to find harry, she'd have to do some serious looking around. When he was asked if he was worried about running into Taylor at the awards show, Harry said: "I'm not worried about seeing her at all. She's a sweet girl, you know. I don't have a bad word to say about her."

Britney Spears was seen having dinner on Valentine’s Day with a mystery man – and we now know his identity… sort of. His name is David and he’s 27 years old. He works for a law firm, but he's not a lawyer. He does "field research". David and Britney met through friends. They were seen together over the weekend Sherwood Country Club. He's a big golfer and she is thinking about becoming a member of the country club. As for whether they're dating though... her reps have been dodging the issue for days… so that makes it seem like they are.
