Justin's New Smokin' Hot Chick

Justin Timberlake is playing a game of musical hotties, and it's Scarlett Johansson who's once again landing -- and grinding -- in his lap.

The pop crooner had reportedly moved on from Scarlett (who was just named number two in AskMen.com's 99 Most Desirable Women of 2007), and onto Jessica Biel (#5 in the same list). But down in Miami for the Super Bowl, says In Touch, it was JT and Johansson spending "the whole weekend together," and meeting up for a 3:00 AM "nightcap" at his Delano Hotel bungalow on Saturday.

The pair were also seen at the Hennessy postgame after-party at Mokai, "dancing and

whispering in each other's ears." Page Six adds that as they were leaving, Justin was standing against a wall, and got a suggestive grinding from ScarJo.

Whose fault is it, really, if you take TRIMSPA and you're still fat? TMZ broke the story yesterday that a girl named Janet Luna -- apparently a minor -- is suing the diet company and spokeswoman Anna Nicole Smith, claiming that the product is bogus. Luna alleges the promise that TRIMSPA causes "rapid and substantial weight loss" is "false or misleading."

But we did some checking. On the TRIMSPA website, it says, clearly, "TRIMSPA products may not work for everyone," and that the average weight loss using TRIMSPA X32 was seven

pounds, not the 80 that Anna Nicole says she lost. Plus, there's this: "Not for use or sale by persons under 18 years of age." Will that get TRIMSPA off the hook? The jury is out.

OJ Simpson says that he doesn't much care what anyone thinks of the book in which he lays out the murder of his ex-wife Nicole Brown Simpson, because, frankly, he just took his money and ran. In an interview with the Palm Beach Post, he claims that he told Judith Regan, the would-be publisher of "If I Did It," that he hoped the book would never see the light of day. Even so, he tells the Post's Page Two that "there were a lot of inaccuracies about ... how I would have done things." When asked if he was surprised by the public outcry over the book, Simpson said, "I don't care. I got paid just the same." And pressed for a payment figure, Simpson was shushed by a handler and disappeared.

Mariah Carey loves Beyonce -- but who the heck is J.Lo, anyway? Screaming Mimi was, according to Faded Youth, giving an interview to a German television station, and when asked her opinion of Beyonce, gushed about "how beautiful and sweet and talented" she is. But when the conversation turned to Lopez, Carey's tune changed. She looked uncomfortable and said, "I don't know her." No word on what might've caused a rift between the two divas, but speculation is that it might have something to do with using the same samples for the same songs.

Score one for the forces of self-realization. "Laguna Beach" queen bee Lauren Conrad says that she doesn't want to act. Repeat: She doesn't want to be an actress. "I tried it," she tells Ben Widdicombe. "It's not that fun, and I'm not that good at it." ... Jason Priestly and wife Naomi Linde are expecting their first child this summer, says People, as first reported by Liz Smith. The couple were married in 2005. ... John Mayer made a sweet sixteen wish come true for a young fan. As People reports, the rocker kissed the birthday girl after she held up a sign at a concert in Oklahoma saying that she'd never been kissed. ... Apple Inc., the computer company, and Apple Corps, the Beatles' record firm, are burying the silver hammer in their long-running trademark suit. No word yet on whether Apple's iTunes will carry Beatles songs.
