Remember when you were 15? Chances are good you were awkward and insecure and maybe fighting some baby fat or acne because that's pretty much what adolescence is all about.

Unless you're Ava Sambora. And then you win the DNA jackpot and get to skip all that nonsense.

The pretty teenager -- the daughter of actress Heather Locklear and Bon Jovi guitarist Richie Sambora -- has done some modeling before, and she's about to make her feature film debut in the Judd Apatow comedy 'This Is 40.'

She took her mom along to the premiere on Dec. 12, and holy crap is this girl about to cause her parents a lot of sleepless nights.

Or ... maybe not.

Having a rock star as a father can be a blessing or a curse -- and in this case it seems Ava struck gold (again). "She's dating. I have a nice big house and I make sure all the kids come over to my place so I get a chance to [meet] them," he once told 'Access Hollywood Live.'

And it's a good thing he's so vigilant, because the red carpet photos from the 'This is 40' premiere and the candids on Ava's Instagram page show she bears a stunning resemblance to her still-gorgeous mother.

Bottom line: They sure don't make 15-year-olds like they used to.
