Look out Trey Songz! Over the weekend, fellow R&B crooner Mario posted a photo on Instagram of himself in his undies. Apparently, the singer felt a little brolic and wanted to show the ladies his, um, package.

"Ladies only," he wrote along with the revealing pic. "I had a dream that I would play in the next spartan movie so I woke up like this."

So far, Mario has garnered over 4,000 likes on the photo from his followers. It pales in comparison to Songz’s 200,000-plus likes for his underwear photo, but who’s counting.

Are underwear selfies the new trend for R&B artists?

A quick scan of Mario’s Instagram feed shows that the 'Somebody Else' singer has posted several photos of himself in his underwear way before Songz did for Calvin Klein’s hashtag campaign.

Either way, reactions to Mario’s underwear selfie have been mixed.

"Lol he wanted to show off his body (nice) but delivery is a bit corny," wrote one follower, while another fan commented, "Yaass hunny!! Sing to me baby!"
