(Reuters)

Here's the skinny:

See-through gown alert! Paris Hilton wore a very sheer dress to P. Diddy's pre-Grammy party in L.A. (Because when the public has already seen you naked, why pull any punches? Right?) Is it a trend? stepped out in a sheer dress this week as well.

Speaking of Hilton, her old pal Nicole Richie gave a Marie Claire interview where she kinda hinted that she no longer hangs out with the hotel heiress.

LeAnn Rimes wore a low-cut leather dress to a Billboard party in Los Angeles and posed with husband Eddie Cibrian next to a giant statue of a disembodied foot.

A Miami model says Justin Bieber shared his deepest fears with her just hours before he was arrested for DUI. (And merely moments before he left with another, completely different model.)

Also, TMZ thinks somthing fishy might be going on with Bieber's arrest. They learned that he had barely any alcohol in his system, despite the police report reading otherwise.

Tori Spelling's husband Dean McDermott has checked himself into rehab amid rumors of infidelity. But if it weren't for infidelity, those two in the first place.

Jimmy Fallon will welcome Michelle Obama to "The Tonight Show" during his first week as its new host.

Nicki Minaj is miffed about being retouched on the cover of ESPN magazine. Specifically, she doesn't like the fact that they gave her a five-head.

Singer Mary J. Blige's father is in critical condition after being stabbed in the neck.

In an odd twist of fate, the doctor who delivered Prince Charles also delivered his wife, Camilla. So who knows? Maybe the doctors who delivered us also delivered our future second spouses!

"SNL" newcomer Colin Jost was named the new co-anchor of "Weekend Update" (alongside current co-anchor Cecily Strong) as Seth Meyers prepares for his new gig on "Late Night."

Carrie Fisher told TV Guide that she, Mark Hamill and Harrison Ford will all be returning for the next "Star Wars" installment.

And finally, Lay's potato chips might soon come flavored like sushi or corned beef. Finally.
