US TV star Jay Leno has put a bounty out on a family portrait of actress Jessica Alba after learning the sexy star was once a fat nine-year-old.

Leno, the host of The Tonight Show, has offered $10,000 (GBP5,550) to anyone who can serve up one photo the SIN CITY star wants no one to see after she recalled a humiliating picture experience as a child.

Alba told Leno, "Picture day comes and my mom did full glamour shots (of me) - like hair and make-up; big hair, lots of make-up. I'm nine and I'm huge."
