As brother Joe once predicted, the Bonus Jonas is also a ladykiller.

Frankie Jonas is all grown up and officially going to prom! The 17-year-old sibling of Kevin, Joe and Nick Jonas attended the Carroll Senior High School dance in Southlake, Texas on Saturday with his girlfriend Austin.

And like most regular high school students, prom was all about the photos. Frankie and Austin posted several pictures on Instagram, and no awkward prom poses were captured.

“Dabbing our way through prom,” the youngest Jo bro captioned one photo.

Not only does Frankie look dapper in a suit, but the teen also knows how to woo a gal.

Dressed as Marvel sidekick Bucky Barnes, he asked his girlfriend to the dance using punny posters that were of course in keeping with the superhero theme.

“I’d be Red Scared if you didn’t make me the Bucky-est man on earth by going to prom with me,” it read on Frankie’s sign.

Frankie’s first TV role was a recurring role in the 2009 Disney Channel original series, Jonas L.A., alongside his brothers.

And as Nick once said it best, “I feel old.”
