Bruno Mars Spotted Slinging Drinks at Boston Rooftop Bar

If you weren't lucky enough to see Bruno Mars live at MGM Music Hall at Fenway this past weekend, then maybe you were even luckier and had him serve you a drink on Sunday.

The Grammy-winning singer had himself a Sunday Funday at the Envoy Hotel's rooftop bar when he stepped in to sling some drinks for very excited guests.

Now don't start thinking he just likes to moonlight as a bartender. He had a bit of an ulterior motive. Bruno made sure to only serve guest shots of his luxury rum brand, SelvaRey Rum.

Not that anyone was complaining.

Though the hotel and the singer have yet to post any photos from Mars' short stint as a bartender, fans were not so tight-lipped and were happy to fill their socials with photos of the unreal moment with the "24K Magic" singer.

Clearly, Bruno is cool with doing whatever makes him happy in the moment and it appears he had a pretty good time himself before playing his third and final sold-out show at the new Boston music venue.

It also wasn't the first time he surprised Massachusetts fans with an unusual September sighting.

At this time last year, he was the wedding singer for some seriously swanky Cape Cod nuptials at the Chatham Bars Inn.

Bruno's next tour stop will be down under in Australia, so now we'll all just have to wait and see if September 2023 brings Massachusetts another buzz-worthy Bruno sighting.
