Justin Bieber Serenades Selena Gomez at Hotel Bar

Who's "Sorry" Now?
Justin Bieber is busy laughing his way to the bank with 'Purpose' money.

A fan at the Montage Hotel bar happened upon Justin Bieber and Selena Gomez spending time together Friday night.

Instagram user, eatprayphoto, was out with girlfriends, just enjoying the ambiance of the relatively empty bar when she noticed Bieber and Gomez near the bar piano.

Things got even more interesting once 21-year-old Bieber began singing “My Girl” to the 23-year-old Gomez, much to the delight of eatprayphoto, who managed to capture the moment on video and post it to Instagram.

@justinbieber singing my girl to @selenagomez….is this real? Pure magic.

In fact, Selena also snapped a pic of the ladies posing with Bieber and received photo credit in the caption.

One can only wonder of this chance encounter between the two exes: “What Do You Mean?”
