The 17-year-old singer will not only act when he makes a cameo on the CBS sitcom, which stars "Arrested Development" actor Will Arnett, but he's also going to bust out in song.
During the episode, dubbed "Bahama Mama," Mahone will play the teen version of Adam (Nelson Franklin) in a flashback scene. The adult version of Adam is Arnett's brother-in-law on the show, which also stars former "Glee" actress Jayma Mays as Arnett's sister and Franklin's wife.
And judging from this exclusive photo, Mahone will be going dorky chic for his appearance, wearing thick-rimmed glasses and a varsity jacket. He also somehow ends up in a van, decorated with beads and various accessories.
Mahone previously appeared on Nickelodeon's "Big Time Rush" in 2013, a cameo he hoped would prepare him for future acting gigs. "It was a really fun thing to do and BTR even taught me some acting tricks so I'll be ready for my next role!" he said in a statement last July.
