Irina Shayk strutted down the runway at the Victoria’s Secret Fashion Show with a secret bun in the oven, and at this rate, she’ll be back on the catwalk in no time.

Just four months after welcoming her first child — daughter Lea De Seine — with actor Bradley Cooper, the Russia supermodel took to Instagram with a mirror selfie that showed off her toned abs.

Irina, 31, modeled a set of lacey white lingerie in the shot, simply captioning the post, “Summer with @intimissimiofficial.”

The new mom’s jaw-dropping post-baby body is no shock. Less than a month after welcoming her daughter with Bradley, 42, Irina shared a bikini snap on Instagram, showing off a toned set of post-baby abs as she relaxes on a lips-shaped raft.

“Pre-sunset #currentsituation,” she captioned the sunny pool shot.

The new parents recently joined Allison Williams (and her husband Ricky Van Veen), Anderson Cooper (and his studly partner Benjamin Maisani), Diane von Furstenberg and Andy Cohen for an island sojourn in Tahiti, their first public outing together since they welcomed Lea in March.

While the guest list was full of plenty of A-listers, the connections actually run very deep. Andy and Diane are longtime friends and have vacationed together in the past while the designer is also good friends with Anderson's mother, Gloria Vanderbilt. Irina has also worked with Diane for many years, often walking in her fashion shows.
