'Cougar Town''s Courteney Cox: Zac Efron Would be Perfect Prey

ET's Thea Andrews is first on the set of the much-buzzed about "Cougar Town" for a little one-on-one with series' star Courteney Cox, who fills the ET correspondent in on the litmus test for spotting a cougar.

"You know you're a cougar when you're attracted to your son's friends. You know you're a cougar when you're attracted to your daughter's -- who's five -- idols, which is where I come in," Courteney jokes.

Courteney's daughter Coco is five and she has a huge crush on "High School Musical" star Zac Efron, who the former "Friends" star says would be ideal prey.
