Former Baywatch star David Hasselhoff celebrated his 59th birthday on Saturday by making a splash in Vegas with his Pamela Anderson look-a-like girlfriend Hayley Roberts – who is nearly half his age at 31.

David arrived in Las Vegas on Saturday and immediately headed to the Encore Beach Club at Encore Las Vegas where he grabbed a red lifeguard can and jumped up on a lifeguard tower to reenact his Baywatch days.
