Cookie who? Nick Jonas sings with ‘Sesame Street’ characters

Nick Jonas is heading back to the small screen for a trip down memory lane…or should I say a trip down Sesame Street. The Wyckoff-born heartthrob is making a guest appearance on the classic childhood series alongside Cookie Monster, The Count and Bert with a fun sing-a-long to the show’s original song, “Check That Shape.”

The 23-year-old “Chainsaw” crooner is using his pop vocals that ladies love to win over the hearts of young children and ultimately help them learn about the different types of shapes in the world, like pentagons and octagons. I’d go back to school in a heartbeat if Nick was the professor teaching the lesson. Here’s the full video:

Catch Nick’s Sesame Street episode Saturday at 9 a.m. on the program’s new home, HBO.

Although he won’t be singing about shapes, get ready to sing your heart out and dance your ass off when Nick releases his fourth studio album, Last Year Was Complicated, is set for release June 10.
