Cardi B Performs in Bathrobe at Bonnaroo After Outfit Splits

Cardi B‘s rainbow-colored jumpsuit couldn’t take the pressure of a full concert worth o’ booty shaking, but she made sure the show went on … slightly more covered up.

The rapper had just taken the stage Sunday night at the Bonnaroo Arts and Music Festival when — a couple songs into her set — she suffered a wardrobe malfunction … a split right down the middle of her ass.

Cardi left for a few minutes after announcing her outfit had ripped, but after the crowd entertained themselves by singing “Old Town Road” … she reemerged in a white bathrobe and declared, “We gonna keep it moving, baby.”

Even with her setback, Cardi’s set was a super quick 45 minutes, but was jam-packed with all of her hits … including “I Like It,” “Money” and “Bodak Yellow” to close it out. She also vowed to “keep it sexy” and managed to do so … even in a robe.

As we reported, Cardi’s had to cancel some shows lately due to complications with her recovery from cosmetic surgery — lipo and a boob job.

Good to see her back on the road — but we know Dr. Terry Dubrow‘s concerned with how long it’s taken Cardi to bounce back.
