Name at birth: Scott James Vincent Baio
Scott Baio had his first starring role in 1976, appearing with Jodie Foster in the kid comedy Bugsy Malone. He joined the cast of the popular TV series Happy Days in 1977, playing Charles "Chachi" Arcola, and starred with Erin Moran in the spin-off series Joanie Loves Chachi in 1982. Baio also starred in the TV series Charles in Charge, Baby Talk and Diagnosis Murder (with Dick Van Dyke) in the 1980s and '90s. As he continued to make occasional TV appearances, Baio jumped from teen idol to reputed ladies' man, dating Pamela Anderson, Brooke Shields and even Liza Minnelli (15 years his senior). He parlayed that reputation into a VH-1 "reality" series, Scott Baio is 45... and Single, in 2007.
In 1997, around the same time that comedian Chris Farley died, a rumor started that Baio had been killed in a car accident. The rumor is false and without a clear origin.
