The "Levels" singer shows off shocking new look on the Scream Queens set.
In case you weren't already excited for the two-hour Scream Queens premiere, Nick Jonas is giving you even more reason to tune into Fox's next hit TV show.
Jonas, who turned 23 Wednesday, was spotted on the set in New Orleans, Louisiana, dressed in khaki pants, a striped T-shirt and a puffy green vest. Wearing a brunette wig and a full-on faux mustache and beard, the "Levels" singer was barely recognizable.

Earlier in the day, he was seen without the facial hair and wig at the set's fraternity house, rocking a much more polished look in a navy blue and red sweater.
Jonas plays Boone, the best friend of Chanel Oberlin's (Emma Roberts) college sweetheart, Chad Radwell (Glen Powell). And given how put-together and preppy Jonas looked in his first character photos, we're not sure what may have driven to this latest unkempt status.

The series, created by Ryan Murphy, Ian Brennan and Brad Falchuk, centers around the "world's meanest sorority." Twenty years after a mysterious death shakes up Wallace University, another murder takes place following a Kappa sorority pledge gone totally wrong. Also starring in the show are Lea Michele, Keke Palmer, Ariana Grande and Jamie Lee Curtis.
Murphy, who created American Horror Story and Glee, promises viewers that they'll be kept on the edges of their seats all season long.
"Every week, it's really like a murder mystery," he teased to ET in March. "Who's going to get knocked off? And who's the killer? And not until the last episode do you find out who it is. And everybody has the motivation to be that killer."
