She only made her Las Vegas residency debut on Wednesday (January 20), but Jennifer Lopez has already suffered her first wardrobe malfunction on stage.

Well, could we really be that surprised considering she has to squeeze in 12 whole costumes into a two-hour show?

Jenny From The Block suffered a split in her sparkly AF catsuit right at the end of her performance after thanking the crowd and taking a bow.

In true form, her costume gave way on the bum – but ever the professional, J. Lo kept things together and continued to soak up some serious applause.

That’s one way to know if your squats are paying off, we guess.

But we all know who’s really to blame here, don’t we? Jimmy Fallon and his infamous Tight Pants sketch.

We’re just going to leave this here…
