Watch: As Gay Twitter Goes Berserk, Benson Boone Apologizes for NSFW Grammys Moment

Singer Benson Boone capped off his Grammy performance of "Beautiful Things" with a salty moment that raised eyebrows. Now the 22-year-old has taken to social media to apologize.

After walking through the Grammy audience dressed in a tuxedo and crooning the start of the song into a microphone, Boone paused by a table where supermodel Heidi Klum and comedian Nikki Glaser were seated. The two women jumped up, grabbed Boone's tux, and tore off his suit jacket and shirt, revealing a pale blue jumpsuit underneath. Boone then reached down and snatched the trousers off, bringing the rest of the sexy ensemble to light.

But that wasn't the moment that took everyone by surprise.

Nor was it the singer's acrobatic moment when he hopped on top of a piano and then launched himself into a forward flip, hitting the stage lightly with a perfect landing. He followed that up with a mid-song backflip in another display of his physical prowess.

After he had finished the song, and as he nodded his acknowledgement to the applause, Boone suddenly reached down, lifted a leg, and, with a mischievous expression, grabbed his crotch and gave it a tug before bowing to the crowd.

Gay Twitter went mental.

The singer has thrilled audiences before with his displays of athleticism – not to mention displays of his sculpted physique; he went viral last summer after leaving a concert venue clad in little more than an American flag-themed Speedo, and his gym selfies are the stuff thirst traps are made of.

But this time the singer felt compelled to offer a word of apology, E! News reported.

"Sorry for adjusting my jumpsuit so aggressively on stage tonight," the outlet quoted Boone posting on his Instagram Story, where his comments captioned a candid shirtless snap; "that thing was extremely restricting in certain areas."

No need to apologize, Benson!
