Wardrobe malfunction -- times two!

Kelly Rowland had a double nip slip during a performance Sunday in West Orange, NJ. The 30-year-old former Destiny's Child member was wearing a revealing, bra-like top that rode up during her performance.

Despite inadvertently revealing herself, the singer, who will be a judge on this season's X-Factor in the UK, seemed in good spirits. "New Jersey crowd was amazing," she tweeted Sunday. "Hope you enjoyed the show and didn't mind the peekaboo. LOL... Stuff happens."

On July 26, Rowland reunited with her former bandmates Beyonce and Michelle Williams for the launch party of her third solo album Here I Am. 

"The inspiration [for the album] was feeling like a woman now, like a grown-ass woman and wanting to express every side of that," she told Us Weekly. "I even tapped into more of a sensual side."
