Zack Morris Is Still Really, Really Hot
Mark-Paul Gosselaar, 39, shows off his ripped body while filming 'Franklin and Bash' in Malibu Tuesday.
The 39-year-old actor -- who on Monday confirmed he's expecting his first child with wife Catriona McGinn -- stripped down to a whole lot of nothing on the beaches of Malibu, which allowed everyone to catch a sneak peek at his seriously ripped body.
Granted, we kind of miss his blond hair from his days playing Zack Morris -- but there's no denying the man still looks mighty good.
Have a look at the evidence in the photos, below.
