The "Saved By The Bell" alum will stop by the ABC comedy as Max's (Adam Pally) "mysterious new roommate," according to EW.
Gosselaar, who also guest stars on the Season 2 premiere of "Don't Trust The B---- in Apt. 23," is not the first '90s heartthrob to stop by "Happy Endings." Brian Austin Green guest starred in the Season 2 finale as a love interest for Penny (Casey Wilson) and will appear in Season 3 as well, Wilson told HuffPost. "B.A.G. is gonna be in the premiere ... and I think he might be back again as well," she said.
