Poor Britney Spears suffered an embarrassing wardrobe malfunction during her Las Vegas show on Wednesday night.

The 35-year-old was performing during her Piece of Me residency on Feb. 1, when her low-cut green leotard slipped to one side, exposing her left breast. Based on video of the incident, it appears as though one of the blonde beauty’s backup dancers accidentally dislodged her outfit. But Brit didn’t seem fazed by the nip slip, finishing her song like a true professional.

This isn’t her first costume mishap on the Planet Hollywood stage. In October, during a “I Love Rock n’ Roll” and “Gimme More” medley, the straps on her bondage-inspired getup broke, and she was forced to clutch her chest until it could be fixed.

Unfortunately, this month looks like it'll be a rough one for the mother-of-two. On Feb. 18, the biopic Britney Ever After airs on Lifetime, and trailers for the movie confirm that it will be a glorified mess. In fact, a prominent scene in one of the promos features the singer getting her head shaved during her 2007 breakdown (the 10th anniversary of which is on the 17th). It also teases clips of Britney in concert, being photographed by the paparazzi, her wedding to Kevin Federline, and that time she repeatedly hit a car with an umbrella.

The Grammy winner’s rep previously revealed that she doesn’t support the movie. "Britney Spears will not be contributing in any way, shape or form to the Lifetime biopic nor does it have her blessing,” a statement to Us Weekly read. But former ‘NSYNC band member Lance Bass, who will be depicted on-screen, said he’ll definitely be tuning in. “I love Lifetime movies. Of course I’ll watch it! I get to see a little me on there,” he shared.
