COULD BE TRUE COULD BE CRAP: Last year, "Us Weekly" claimed JUSTIN TIMBERLAKE cheated on JESSICA BIEL during a steamy, three-day affair with OLIVIA MUNN. Everybody denied it, of course. But now "Life & Style" is picking up where US left off claiming JT is trying to rekindle things with Olivia.A "friend" tells Life & Style she knows this because she's seen several texts from him to Olivia on her phone, all of which were sent in the last few weeks of December. One says, quote, "My relationship is basically over", the another reads "I'm thinking about you", and the third - which she's only seen PART of - starts off with, "You don't know how hard it is . . ."

The source goes on to say Olivia is, quote, "Super flattered, but she's not stupid. She's not expecting it to go anywhere, but she'd love it if it did!"

Speaking of Munn ...her February "Maxim" cover has caught a lot of flack from many who believe it’s far too racy for grocery store check-out lines. The slightly see-through nature of the blue underthingys she's wearing is the culprit ...

WTW???!!! WHO DOES THAT???: It seems CHRISTINA AGUILERA had a wee bit too much bubbly at a birthday party thrown for actor JEREMY RENNER after the Golden Globes this past Sunday night.

Word is Christina decided to sleep it off in Jeremy's bed!!! "Someone comes and tells me she's in my room," Renner reportedly told a group of friends who then blabbed about it to US magazine.

"I run up and open the door and I'm like, 'Um, hi. What are you doing?' She just starts slurring. Her boyfriend [Matthew Rutler] was rubbing her back. Who comes to someones birthday party that they don't know and gets in their bed?!"

DID JENNIFER LOPEZ STEAL HER NEW SONG???!!!:No sooner was the new JENNIFER LOPEZ song, "On the Floor," leaked on the ‘net this week than the accusations of song stealing begin. Many have begun pointing out its striking similarity to a Kat DeLuna song called "Party O'Clock," which came out last year. So is Jlo a song thief?

Well, the truth of the matter is both tracks do feature similar lyrics and melodies, but that might have something to do with the fact that both were produced by RedOne.

A similar situation happened in the summer of 2009 when Kelly Clarkson and Beyonce's released eerily similar tracks: "Already Gone" and "Halo." Clarkson said the guy she worked with on the song, Ryan Tedder of One Republic, also worked with Beyonce and gave her the same backing track to work with as B had.

Here’s a mashup of the Lopez and DeLuna song. We report, you decide …

One last thing on Lopez ... Late night talker CRAIG FERGUSON had this real funny line about her being an "Idol" judge last night ...

IN DENIAL: It seems every day another celeb announces she's pregnant. But HILARY DUFF isn't one of them. Hil's rep called rumors bogus yesterday. Hilary herself tweeted, ""Wow what a way to wake up and find out your pregs! It's just a rumor guys! Not true. But thanks for all the good wishes! Lol."

COVER SHOT: KHLOE KARDASHIAN gets muzzled on the cover of YRB magazine. What are they trying to say???!!! ...

OMG!!! ...Did you hear what Khloe's husband LAMAR ODOM said about her in this month's "Playboy" interview??? Quote, "When people see us in person, they see Khloe's not small." WTW??? Did he just call her fat!!!

Lamar was answering a question about the existence of any intimate videos of he and his Khloe when he made the "not small" comment. The answer, by the way, is no one doesn't exist because their size, he said, would scare people.

CHARLIE'S SHEEN-ANIGANS:According to RadarOnline, CHARLIE SHEEN'S drug-fueled weekend in Vegas earlier this month reportedly cost him $26,000 for three escorts.

Charlie, who earns $1.8 million an episode for Two and a Half Men, handed one lady 10-K for a four-hour, um, date. The other two got $8,000 each. Adding to his expenses was his $40,000 a night suite at the Palms Resort. No word on how much the cocaine cost.

No question that's a lot of dough, but if anyone can afford it, it's Charlie Sheen. Check it out ... He gets $1.8 million per episode. When you deduct commercials, each episode is 21 minutes long. So, by my calculations, it took him about 18 seconds to pay his Sheen-anigans.

For you super-serious math geeks, here's how I arrived at that conclusion: 21 minutes = 1,260 seconds. $1.8 million divided by 1,260 = $1,428.57 per second. $26,000 divided by $1,428.57 = 18.20 seconds. See, I’m not as stupid as I look!
