For Andy Cohen's 50th birthday celebration, John Mayer stopped by to host Watch What Happens Live and had a delightful surprise for both the host and the audience. Mayer said he put his "nose to the street" and found out one of Cohen's favorite songs is Diana Ross's 1979 hit "It's My House," so he decided to perform an acoustic cover of it for his friend.
Cohen's reaction to watching Mayer serenade him sums up exactly how you'll feel after playing the video above. "I have done nothing but learn that song in the last 48 hours," Mayer said. "I have eat, breathed, and slept 'It's My House.'" Fair warning, you'll probably want to replay it at least once (or twice), because Mayer's voice is just that sweet.
