The rock icon and pop superstar finally met.
Bert and his old pal Ernie dropped by 'Elle' to play the popular 'Song Association' game.
The pop star also sent a holiday note to her fans.
"This 11 year old (11,000 year old soul) blows me away," P!nk captioned the video of Willow Sage Hart performing at her first-ever recital.
The singer wore a red mini dress with a red bow across the chest, complete with a red garter and black boots.
