John Mayer dresses up in a bear costume to perform with Sheryl Crow [PHOTO, VIDEO], Sheryl Crow shocked John Mayer on tour by appearing onstage in a skimpy bikini, one day after he surprised her by dressing up in a bear costume.

On the final stop of their six-week tour, Crow got her revenge and came out on stage during Mayer's set sporting a sexy lilac-coloured bikini to purposely distract him. Mayer wanted to play a practical joke on the star on the night before and when the singer called him to the stage to join her in singing My Favorite Mistake as per usual, he stunned her by appearing in a hairy bear suit.
