BTOB's Minhyuk experienced a wardrobe malfunction of the most embarrassing kind at a comeback stage performance for M Countdown.
The 24-year-old star suffered the awkward clothing fail during a vigorous dance interlude during a rendition of the group's single "It's Okay" for the show's special live episode in Gwangju.
While the majority of their choreography maintains a steady pace, the dance break in the middle of the song picks up speed and sees the members giving it their all.
And in Minhyuk's case he gave it jus a little bit more! When he spread his legs during one of the moves, his navy trousers ripped to expose bright red underwear.
Luckily he spared any blushes with his choice of boxer shorts, but he still quickly took to his Twitter account to apologize for the incident.
He added that it was actually the group's manager who packed their clothes that day, selecting two pairs for him -- red and leopard print.

Still, he also saw the funny side, suggesting that perhaps they should make a song called "Open." And the stage snafu actually got the band more press than ever, becoming one of the most searched for videos on Naver and making headlines everywhere in Korea.
Minhyuk added, "I'm #Okay... Everyone please give lots of love to #Open. #CrisisToOpportunity."
