Little David Silver is a far cry from his West Beverly High days -- Brian Austin Green turns the big 4-0 today!
Green landed his breakout role on the popular drama, "Beverly Hills, 90210," where he played the geeky yet adorable boyfriend of Tori Spelling (Donna Martin).
Since starring on the soap, Brian's appeared in a number of TV series -- most recently "Terminator: The Sarah Connor Chronicles," "Desperate Housewives" and "Anger Management."
But Green's biggest accomplishment thus far has to be the birth of his son Noah, who he welcomed with wife Megan Fox last October.
No matter what the actor does, we'll always remember him as the adorable high school DJ. Have the rest of the Peach Pit gang fared as well?
