John Mayer and Queen Latifah joined forces with A-list Muppets to promote a new PBS special. We can't wait to see the program when it premiers on April 1st, but in the meantime, here are some of our other favorite celeb sightings on Sesame Street.
Elmo scored big when he got to hang with David Beckham who starred in the "Word of the Day" segment to teach us about 'persistence'. We're not giving up on you any time soon, Becks.
Former Playmate Jenny McCarthy's bugged out when her word of the day was 'insect'.
Jack Black tickled us with a lesson about the shape "with eight fantastic sides and eight awesome angles." He of course was describing that cornerstone of mathematics, the Awesome Octagon.
It was fitting that Heidi Klum's word of the day was 'compliment', as the supermodel is probably no stranger to them. Elmo was positively gushing.
"Superbad" star Jonah Hill hit The Street to teach kids an invaluable lesson about rocking an awesome moustache.
After fashion icon Sarah Jessica Parker went downtown to Sesame Street, ladies across Manhattan began inexplicably dressing like red furry-handed puppets.
LL Cool J gave big ups to Elmo Cool J.
Elmo and everyone else on Sesame Street could barely hide their crushes on Jessica Alba. Everyone except Burt & Ernie, that is.
Though Bert & Ernie LOVED it when Neil Patrick Harris appeared on Sesame Street as a 'Fairy Shoeperson'.
