They're almost back! AOA released the fourth video trailer for their forthcoming summer single, "Heart Attack", and it doesn't disappoint.
The eight girls tease viewers in the short clip, changing into skimpy lacrosse uniforms in front of the camera as they stretch and prepare in a bright locker room setting.
Yuna, 22, spares no blushes with a flirty moment when she slowly puts on her clothes over a white sports bra.
The 36-second video also introduces some of the dance moves fans can see in the final release, including an interesting boob-tap dance. Choa, Mina, Seolhyun and the rest of the girls all look flawless in white cheerleader outfits.
