Sia is notorious for rocking over-the-top wigs that cover her face, but now the singer is (briefly, at least) shedding her disguise. While she was on set of an upcoming Sesame Street episode for their show’s #SesameTakesLA project, Sia decided to peel away a few inches from her infamous two-toned wig.

“having the BEST time today at @sesamestreet,” was the caption of the "Unstoppable" artist's fun photo with Cookie Monster, as she rocked an oversized candy-striped bow and a clown nose. Sesame Street also posted a few adorable photos of the puppet cast donning the singer's wig on Instagram.

No word of when Sia's Sesame Street episode will air, but she does join the ranks of Jason Derulo, Little Big Town and James Corden who recently filmed for the children's show. She also lent her voice to cover a few Beatles tracks for Netflix's animated series, Beat BugsLook out for its first season in August.
