At only fourteen years old, Chloe Grace Moretz is easily more mature than many people her age, which can make dating a challenge. On 'Chelsea Lately' (Weeknights, 11PM ET on E!), she reaffirmed her infatuation with Ryan Gosling from a magazine interview.

"I think everyone's a little obsessed with him," she said. Handler agreed with her on that point, but noticed something else happening as well.

"You're very flirtatious," Handler told her. "You are. I'm a girl and I can feel it."

As for who she's going to date, though, Handler asked if she suspected she would date older men. "I'm thinking 70s," Moretz quipped.

John Travolta won't be jumping on the 'Glee' cameo train. The 'Grease' star told 'Entertainment Tonight' he was asked to cameo but turned down the offer.

"They've asked, but when I do musicals I train for six to nine months ... and a show like that is an on-demand thing," Travolta said. "I really have a criteria or a pride that I would wanna knock 'em dead, and I don't think I'd knock 'em dead in a week."

Travolta's 'Grease' co-star Olivia Newton John has appeared on the show twice. Among other high-profile guests, Oscar-winner Gwyneth Paltrow has a recurring role on the series and Anne Hathaway dreamed up her own role and pitched it to producers.
