Ava Sambora, the 13-year old daughter of Heather Locklear and Richie Sambora, is debuting in Judd Apatow’s next film which is a spin-off to the hit comedy “Knocked Up.”

Sambora will be joining Paul Rudd and Leslie Mann, both reprising their roles from “Knocked Up” in the new film called “This is Forty.” Mann’s is Apatow’s real life wife, and their daughter, Maude will play Mann and Rudd’s child in the film.

Sambora will take the role of Maude’s best friend. It’s just a little role but it’s certainly a good start for the young model who has “acting” in her blood.

Also in this film is Melissa McCarthy from the critical and commercial hit “Bridesmaids.” And yes, Megan Fox, will make a cameo in this film.
