Austin Mahone to Guest Star on The Millers: Find Out Who He's Playing

Exclusive! Teen heartthrob will appear opposite Will Arnett on his hit CBS sitcom as a young version of Nelson Franklin's character

Cue the screaming girls!

Teen singer Austin Mahone is set to guest star on CBS' new hit sitcom The Millers, E! News has exclusively learned. 

The 17-year-old will make his network TV acting debut in an episode set to air later this season in a pretty juicy role: He's a blast from the past!

Mahone will play a young Adam (Nelson Franklin) in a sure-to-be hilarious flashback on Will Arnett's freshman hit. Adam is Debbie's (Jayma Mays) husband and Arnett's brother-in-law on the series.

Funnily enough, Mahone, who appeared as himself on an episode of Nickelodeon's Big Time Rush, is often compared to Justin Bieber, the ultimate teen heartthrob who also made his acting debut on a CBS hit, CSI: Crime Scene Investigation. (His character was shot and killed in his second appearance.)

Also set to appear on an upcoming episode? Former Superman Brandon Routh, who we exclusively reported will be playing Officer Davis, a handsome police officer who is investigating a string of petty thefts in Nathan (Arnett) and his mother Carol's (Margo Martindale) neighborhood. 

The Millers' latest episode tied a series high when it scored a 3.3 ratings in the adults 18-49 demo. The sitcom, which also stars Beau Bridges, received a full-season pickup from CBS after just three episodes. 

The Millers airs Thursdays at 8:30 p.m. on CBS.
