BAYSIDE HIGH REUNION

Regrouping for their PEOPLE shoot for the first time since the show wrapped in 1994, the cast of Saved by the Bell – (from left) Lark Voorhies, Mario Lopez, Tiffani Thiessen, Mark-Paul Gosselaar and Elizabeth Berkley – easily picked up where they left off. "We're still very close for a cast that's known each other 20 years," says father-of-two Gosselaar, who now stars on TNT's Raising the Bar. "I think that will continue."
