Heather Locklear's 15-year-old daughter Ava is the spitting image of her famous mom!

The two walked the red carpet together last night for the Los Angeles premiere of "This Is 40" -- where the gorgeous teenager looked just like her mother did back in the '80s.

Ava is Heather's daughter with rocker Richie Sambora and has already modeled for his clothing line, White Trash Beautiful. She also makes her film debut in the new Judd Apatow film.

Take away Heather's '80s hair in the photo below, and doesn't Ava look like her?
