Lily Collins and Zac Efron
have been tight-lipped about their relationship since spending Valentine's Day together
but that hasn't stopped the Mirror Mirror
star from talking about boys – in general.
"Prince Charming is someone that can make you laugh no matter what," Collins, 22,
told reporters Tuesday during a press conference for the film in Los Angeles. "The thought of them makes you smile."
So does Efron fit the bill?
The actress explained that she was speaking "generically" – but shared a few other traits she admires in a suitor.
"[I'm looking for] someone that's open to spontaneity and not close-minded – and makes you feel like being you is enough," says the actress, who was previously linked to her Abduction
costar Taylor Lautner
As for Efron, 24, he told reporters recently that laughter is key for him, too.
"I like humor and spontaneity, and something you wouldn't expect," he told reporters during a recent press conference for his film, The Lorax
. "I'm a big practical joker, and you can make [practical jokes] very romantic."
Meanwhile, Collins stepped out on Tuesday night to celebrate her March Nylon
cover at Beverly Hills eatery Scarpetta. Although Efron wasn't there, Collins did chat with one of his close friends, actor Ryan Rottman.
