It's no secret that megastar Julia Roberts recently had a son. But who woulda thunk he'd already look like Ryan Reynolds?

"Most of the time when I say that I'm doing a movie with Julia Roberts people would say, 'Oh, you're a couple,'" "The Nines" star said of the laughs he gets from telling friends about his new movie, "Fireflies in the Garden," which he stars in alongside Roberts. "It kills me. Let me have a love affair with Julia Roberts. That'd be fantastic! Sadly, no, she's my mother."

Just because the show was over, that didn't mean the stars were going home. The proverbial after-parties took center stage in Hollywood last night, post-MTV Movie Awards. We hit the clubs and report back with our exclusive observations.

A couple of the "Fantastic Four" cast -- we'll call them the Terrific Two -- Chris Evans and Ioan Gruffudd partied at the official MTV function held at Universal Studios. Porno King Ron Jeremy and "Hairspray" star Amanda Bynes were also in attendance. Over at Sugar, they sure were shady at the door to Rihanna's party. The doormen irritated Jay-Z when he was trying to make his entrance and even made that sexy Nicole from the Pussycat Dolls wait several minutes to enter.

Inside, the woman of the night -- Rihanna -- shunned the VIP section in favor of showing off her drop-dead, any-guy-would-want-to-marry-me-now-knockout red dress. On the dance floor, she danced to her own music, Sean Paul and Beyonce. Meanwhile, another cutie was in the building: "Entourage" member Lauren London. Funnyman Chris Tucker cooled out with Giant Magazine Editor-in-Chief Smokey Fontaine (Giant sponsored the party in celebration of Rihanna being their current covergirl) and another jokester, Guy Torre, was seen shaking hands and rubbing shoulders as well.

For a lucky few, the MTV Movie Awards are a chance to take home a fabled golden popcorn. For others, it's just a chance to meet other famous people and get your picture taken with them. Appropriately enough, our cameras caught a lot of the latter: below, see "Rush Hour 3” star Chris Tucker hanging with the legendary Sam Jackson, "The Office" star John Krazinski posing with "Fantastic 4” star Chris Evans, fellow "F4” castmember Ioan Gruffudd staying cool with "Hairspray" lead Zac Efron and Paris Hilton going from walking-to-limo to model pose in a matter of seconds.
