Kaia Gerber wore a little black dress to boyfriend Austin Butler's event

The 22-year-old DNA Model opted not to pose on the red carpet solo, or with the 32-year-old Oscar nominee, as to not draw any attention away from his big night.

Austin Butler shared a tender moment with girlfriend Kaia Gerber at the premiere of The Bikeriders. The actor, 32, kissed his stunning model/actress girlfriend, 22, in a viral video.
