The return of China-eyes. Jen Aniston, miserable. What's new? Katy Perry gets peed on, while the Octomom remains bewildered and horrible. Plus, Twilight!!!

• Not such good news for Kanye West: He was charged with misdemeanor battery, grand theft and vandalism yesterday in connection with the fight he had with a bunch of photographers at LAX back in September. He could face up to 2 1/2 years in jail if convicted, although that's highly unlikely. And since they're not felony charges, he isn't expected to appear in court when he's arraigned on April 14. [NYDN, LAT, AP]

Cannibals will soon roam the earth, as will comedians. Jennifer Aniston and dogs are Mother Nature's favorite creations. Audrina Patridge will never, ever die. Your in-town-for-pilot-season friend will never, ever leave.

Padma claims she's innocent, the Spellings are fighting again, Matt Damon's wife married better than you did, Drew Barrymore's sucking face again, Rihanna's gonna be in a movie, Jennifer Aniston's definitely not sucking face again.

• Lindsay Lohan certainly had an eventful weekend. After a judge issued a warrant for her arrest on Friday, Lindsay had a meltdown on Twitter and ended up in a fight with Sam Ronson that was so intense, the cops had to be called. It's not over yet: She's scheduled to appear in court today, although she may not show. [People, Gawker, TMZ, NYP]

• Gwyneth Paltrow and her trainer Tracy Anderson are having trouble finding people to pay $4,500 to join their new Tribeca gym. What a surprise. [P6]

• Mandy Moore and Ryan Adams got married on Tuesday in Savannah. [Us]
• Breaking! Katie Holmes has long hair again! [DM]

Bad couple day: Robert Pattinson's Tina Fey lust would be inappropriate, except she started it; there's a conspiracy against the Rihanna-Chris Brown reunion; and John Mayer maybe dumped Jennifer Aniston.

So Jennifer Aniston spent £40,000 on a haircut. More accurately, Fox paid for it. These celebrity extravagances makes the Hollywood ecosystem run, but with the economy crumbling, they are beginning to ask why.

• If you've noticed Jennifer Aniston's hair looking even more perfect and shiny lately, it's not your imagination. She reportedly spent $50,000 to have her hairstylist accompany her around the world for the Marley & Me's premieres. [DM, P6]

• Jennifer Lopez borrowed $50,000 worth of jewelry to attend an event last week, but never gave it back. [P6]

• A bunch of people who attended Madonna, Demi Moore and Ashton Kutcher's Oscars party at Guy Oseary's house ended up leaving early and heading over to the more popular Vanity Fair bash instead. Kate Winslet screamed "Wooo!" at everyone who congratulated her (and later tripped down a small set of steps), a tipsy Natalie Portman flirted with Twilight's Robert Pattinson, and Mick Jagger chatted up every woman that came within two feet of him. [P6, NYDN, E!, Mirror]

The singer was rumored to be a special guest at last night's Academy Awards ceremony but, as happened with the Grammys, the beating she received from boyfriend Chris Brown kept her away.

You've seen the slideshows of celebrities on the Oscar red carpet. Here's how various media moguls dressed up for the big occasion. Lots of really boring black tuxedos after the jump.

• Jennifer Aniston and John Mayer made their first awards show appearance together at last night's Oscars, sitting just 12 seats away from Angelina Jolie and Brad Pitt, although they managed to avoid a run-in by skipping the red carpet and showing up at different pre-show parties over the weekend. [People, NYDN]

• Penelope Cruz and Tom Cruise had an awkward encounter at CAA head Bryan Lourd's house party on Friday night, while Oprah and Gayle King held court at Barry Diller and Diane von Furstenberg's pre-Oscars bash, and everyone "partied like it was 1999" at Harvey Weinstein's gathering.

A picture deal may be all that stands between octo-mom and a foreclosure,just as a clue from daughter Bee is all that stood between Anna Wintour and a new Katy Perry album.

Which is less appropriate: A brand-newmom performing at the Oscars, from bed, or an image-conscious Olympian trying to lay low in a strip club? Decide for yourself.
