The former Grey's Anatomy actress turned movie star Katherine Heigl stopped by Louise's Trattoria for some takeout with her daughter Naleigh on Saturday...

Kat's next flick? One for the Money, and here's the plot: "Unemployed lingerie buyer Stephanie Plum becomes a bounty hunter to make ends meet."

Mmkay, really? Good luck with that one, girl!

And he looks pretty psyched about it! Wouldn't you be? This is Karen Smith we're talking about! Although she didn't go as "a mouse, duh!" - Amanda Seyfried went as a cute puppy!

But why was Ryan Phillippe trying to hide his mystery date on the ride over? Here's what our X17 photog on the scene had to say:

"Ryan and Amanda were definitely together but they didn't really want us photographers to see it. Before they realized we were around, they were laughing and chatting with other people at the party and were obviously a couple. Ryan was really sweet with her -- he had his hand on her lower back for a while when they were talking to another couple. They looked great together."

Who else kinda loves this match? I think they make a cute couple!

Due Date actor Zach Galifianakis sparked up a doobie on Real Time with Bill Maher because, er, maybe he thought his name wasn't in the news enough after the whole Mel Gibson/Hangover 2 debacle? Anyway, watch the hilariousness above!

Who knew the pop princess adored Will Smith's daughter and her new single so much?

Decked out in casual sweats, 28-year-old Britney Spears - along with her boyfriend Jason Trawick - worked on their fitness together at a Beverly Hills gym yesterday afternoon...

Meanwhile, our girl Brit Tweeted "Have you guys seen Will Smith’s daughter @OfficialWillow’s video? SOOOO CUTE!!!!"

Guess that means Ms. Spears is a big fan of whipping her hair, too!

Judd Apatow's All-Star Video from Judd Apatow

This is the most random Funny or Die video ever! Lindsay Lohan is one of the many "non-Jewish celebs" in this Public Service Announcement "not approved by" the American Jewish World Service. Oh, and it's presented by Judd Apatow... go figure!

LiLo puts in the most memorable appearance amongst countless actors - from Ben Stiller to Patrick Stewart - questioning her own appearance in the gig with: "These things pay well, right?"

LOL, Lindsay. LOL. Watch the vid above!

And somehow, the hotel heiress somehow still manages to look like a rockstar! Huuuuuge.

Princess P and her sister Nicky Hilton went out for their second Halloween-themed night in a right... and Halloween isn't even until tonight! The sexy sisters attended the Playboy Mansion's 4th Annual Kandy Halloween party (featuring Tiesto, how rave-y!) last night - along with buddy Brandon Davis, in a psych ward costume...

But how did Paris' outfit look when the evening began?



It's hot either way! Be sure to check out our MONSTER gallery below for more of Paris baring her beautiful bod.

After relaxing in the park on Friday morning with Seraphina, Jennifer Garner spent some time with Violet in the afternoon, and her nearly 5-year-old daughter appeared to be throwing a bit of a temper tantrum!

Today we snapped all three of Ben Affleck's girls on the soccer field, and Violet was on her best behavior as she ran to give mom a hug:



Of course, Jen found a way to solve the problem yesterday afternoon...
