Jeff Vespa/Getty ImagesIt may have been Courteney Cox's celebration last night, but all eyes were on Jennifer Aniston.
Jen hit the premiere of Glamour's Reel Moments at the DGA building in L.A., where Cox's directorial debut—a short starring Laura Dern called The Monday Before Thanksgiving—was being screened, along with flicks directed by fellow first-timers Demi Moore and Kirsten Smith, a screenwriter.
If the press about her dinner dates earlier this week with one-time beau John Mayer was getting to her, it didn't show. Aniston was all smiles and, of course, her hair looked perfect.
However, she did avoid the red carpet by slipping through a side entrance just minutes before the screenings began.
But that didn't keep her from popping into the afterparty at the Chateau Marmont hotel, where she sipped water while chatting in the VIP section with Cox and her hubby, David Arquette.
The night, sponsored by Suave, was a semi-Friends reunion, with Matthew Perry also in the house.
Another attendee was hottie model Matt Felker, Selma Blair's ex-boyfriend and the guy Aniston reportedly went on a date with after she and Mayer broke up. But they didn't appear to have any interaction last night.
Meanwhile, Moore's flick Streak was a family affair. Not only did it star her daughter Rumer Willis, but her daughter Scout was a wardrobe assistant.
"She'd be bringing our clothes to us in our trailers," said the very fetching Sarah Wright, who also starred in the movie. "It was so awesome and cool."
And yes, Moore's husband, Ashton Kutcher, dropped by at least twice during the three-day shoot, Wright said.
As for Demi, she joked about her work behind the camera: "Please don't be too harsh on us—it's our first time."
Courteney also got in on the laughs. Alluding to her canceled FX series, Dirt, Cox took the opportunity to pimp herself out. "I'm available," she said jokingly.
And screenwriter Smith, best known for writing Legally Blonde and more recently The House Bunny, said she's already looking to make her feature film directorial debut after helming the hilarious The Spleenectomy for Glamour.
"I have a book that I optioned," she said. "I probably won't tell you right this second what book, but I am ready to go."
