Britney Spears has once again proven why she reigns as pop royalty after she handled a huge wardrobe malfunction in Las Vegas like a pro.

The 32-year-old singer was onstage performing "Circus" when the back of her tight, sequined leotard unexpectedly popped open.

Although she expressed a look of panic after the zipper tore open, Spears continued on with her choreography without missing a beat. The "Gimme More" singer kept the show going, even twirling around in the arms of her back up dancers a couple of times.

A fan's Instagram video captured the moment and the sheer panic on her face once she realized how close to flashing her audience.

Eventually, one of her dancers zipped her ensemble back up and the "Piece of Me" performer carried on with the show.

Spears has been getting a lot of positive feedback since the opening night of her "Piece of Me" concert in Vegas. A number of stars including Katy Perry, Selena Gomez and Miley Cyrus have attended the show.

The mother of two is slated to continue performing in Sin City for the next two years. According to CNN, the pop star is reportedly earning $300,000 per show and $30 million for the 100 shows through 2015 in total.

During the 90-minute show, Spears dances on a 100-foot stage with 14 dancers and a massive video installation.

She has received criticism for lip syncing through the 21 tracks that she performs throughout her career.
