Posted less than a month after welcoming daughter Lea de Seine Shayk Cooper, the sizzling photo shows Shayk, 31, floating on a giant pool floatie shaped like pink lips with her arms over her head and eyes closed as she soaks up the sun.

"Pre-sunset," she captioned the snap. "#currentsituation"

The model has been dating Cooper since May 2015. The first-time mom announced her pregnancy during the 2016 Victoria's Secret Fashion Show last November, and the couple sparked unconfirmed engagement rumors a month later when Shayk was spotted a ring on her ring finger.

Cooper, 42, has made headlines of his own this week when Lady Gaga shared the first picture from their upcoming film, "A Star Is Born," which will shoot a scene during Coachella.
