John Mayer surprised his good friend Andy Cohen with a special performance.
The 40-year-old singer-songwriter surprised Andy on a special edition of Watch What Happens Live on Sunday night in celebration of Andy’s 50th birthday.
During his appearance, John performed a cover of Diana Ross’s “It’s My House.”
“I wanted to play a song that had some importance,” John said. “I’m going to play a song I think that really sums up the moment, it’s by I think one of your very favorite artists: Diana Ross…in my own inimitable style.”
