Justin Timberlake couldn’t help but admire Jessica Biel’s “abs of steel.”

The “Mirrors” singer, 42, decided to pay his wife an unexpected visit during her “killer Pilates ab” workout in a video she posted on Instagram Monday.

While the Candy actress, 41, went through the motions of fitness coach Ashley Brown’s ab series, a pair of sneakers can be seen entering the frame.

At that point, she hints that Timberlake is the one in sneakers by writing “guess who it is” in the clip.

Timberlake then pokes at Biel’s stomach  — what she referred to in the video as her “abs of steel 😤” — while she exercises on the ground.

The audio of Olivia Rodrigo’s latest single “vampire” cuts out as Biel tells the camera, “That was my man.”

She ends the video by saying, “Have fun y’all 💪.”

The former *NSYNC member is no stranger to crashing Biel’s workout sessions.

In another video she shared on Instagram in June, Timberlake gives his wife a high five after her “cruel single leg squat” workout.

Back in February, while working out with trainer Ben Bruno, Biel wrote about how “some other guy" wouldn't "stop distracting me” in the caption of her Instagram post.

During her workout, Biel begins to smile right before she blurts out, “Justin, stop.” The camera then pans to Timberlake on the other side of the room busting out some hilarious dance moves.

“What? It’s not distracting?” the singer teased. Biel put down her weight while she continued to laugh.
