As if he hadn't proven himself to be perfect husband material already, Nick Jonas showed he's even good with kids in an adorable new skit for Sesame Street.

The 23-year-old pop heartthrob wrote an original R&B song called "Check That Shape" for the Saturday, May 21 episode of long-running children's television show, in which he sings about a variety of different shapes with the help of a muppet chorus.

Leave it to this man to give learning a sexy edge!

"It’s a shape that is so fine. Yeah, that shape drives me out of my mind," he sings as two dancing shapes move out into the shot in front of him. "How it moves and how the shape slides. C’mon, c’mon, let’s count those sides."

"Check That Shape" may have chart potential but it sadly won't be included on Nick's forthcoming album Last Year Was Complicated, which drops June 10.

Check out the video for the catchy tune below:

It's slightly reminiscent of the Dragometry performance on RuPaul's Drag Race, no?
