An appearance on Sesame Street is both a privilege and a rite of passage for any legendary pop star. Remember when One Direction taught us how useful the letter U is? Or Katy Perry crooning "Hot N Cold" with Elmo?

It's Sia's turn to hit the Street and hang with Elmo, Big Bird, Cookie Monster and company — and so far, her upcoming episode on March 25 looks and sounds adorable.

"S is for songs, and I love songs / Don't know what we'd do without 'em! I love songs so much, I wanna sing a song about 'em," she soulfully sing-songs. (And yes, as with all things Sia, it still sounds like a radio smash.)

Perhaps more surprising is the "Move Your Body" singer-songwriter's shorter wig and silly red nose, exposing more of her face than usual — no doubt to appear a little more kid-friendly than her usual obscured look.
