Four months after becoming a mom to new baby Willow with daddy pro-racer Carey Hart, songbird Pink stunned the audience and performers of an experimental play by jumping on stage with a cast member to sing a cover of George Gershwin’s classic, Summertime.

The 32-year-old blonde pop-rocker joined fellow singer Stella Sinclair in the rendition during a performance of Sleep No More and gave the crowd a night to remember.

Wow. Check it.
