WA Entertainment's powerhouse idol group, Mamamoo, is back with the release of their second mini-album, "Pink Funky."

Accompanying the release of "Pink Funky," Mamamoo has released a video for their title track, "Um Oh Ah Yeah" in which members Moonbyul, Whasa and Wheein take on a surprising masculine role. Literally.

The video opens on with Moonbyul surrounded by a team of artists hard at work, transforming the stunning idol into a very masculine version of her usual self. Whasa and Wheein are next, undergoing what has to be hours of pain-staking labor as prosthetics, makeup and hair are all attended to by a dedicated team of professionals. The end result is a total transformation of the trio who then come alongside the very feminine Solar as they take to the set for their actual video.

The transformation of Moonbyul, Whasa and Wheein may come as a bit of a shock to some as the teaser images the quartet released prior to making their comeback kept to the girls' more typically feminine and fabulous look. However even when parading around as men, this quartet can't hide their beauty any more than they can their talent.
