HOLLYWOOD, Calif. — Jessica Alba is the latest celeb headed for Project Runway.

The 28-year-old actress will appear as a guest judge on the hit reality show this Thursday, Lifetime spokeswoman Kannie Yu LaPack tells the Associated Press.

Alba will help judge a challenge where the six remaining contestants have to create an outfit for an "opinionated celebrity," who just so happens to be host Heidi Klum.
