AceShowbiz - Mark-Paul Gosselaar posted on Twitter last month a photo of him and his friend Ben Ceccarelli completely naked while in handstands. The "Franklin & Bash" alum and Ben each wore only a pair of shoes and socks.

Mark-Paul put censor strips to cover their private parts. They named themselves "Team Cocky". The former "Saved by the Bell" star captioned it, "Teaming up with @Piketoon for the @CACrossFit #pairpower competition. @CrossFit. Some would say we've already won."
