*NSYNC’s Joey Fatone & Chris Kirkpatrick Join Bret Michaels For Rowdy Sing-Along in Orlando: Watch

Bret Michaels took one his greatest hits to a new, genre-crossing level in Orlando on Saturday night (Dec. 14) when two pop stars joined him and his band onstage for one especially "good time."

During his set at the Seminole Hard Rock Hollywood's Winterfest in Hollywood, Fla., Michaels got some vocal support from Joey Fatone and Chris Kirkpatrick, who fully embraced Poison's hard-partying vibe. The *NSYNC singers bounded across the stage and joined Michaels on each chorus Poison's 1988 hit "Nothin' But A Good Time."

Fatone and Kirkpatrick doubled as Michaels' hype-men throughout, and spent much the performance running up to the audience and jumping up and down as Michaels took lead on the verses. Kirkpatrick later shared a pic from the side the stage, and gushed on Instagram that he managed to check an item f his bucket list with the impromptu jam.

Michaels will be heading out on the road again with Poison, as well as Mötley Crüe, Poison and Joan Jett and the Blackhearts on their joint stadium tour in 2020.
