Selena Gomez showed off her showgirl persona when performing at Count de Hoernle Amphitheater in Boca Raton, Florida. The "Monte Carlo" beauty wore a gold simmering corset and short ruffle skirt with long train. At one point of the night, she traded her skirt with a cute pink tutu.

The "Ramona and Beezus" star strutted her stuff, belting out songs from new album "When the Sun Goes Down" and some other tracks from her previous works. She was supported by her band The Scene and some dancers in catering the sold-out crowd at the Mizner Park.

Watching from the side stage was none other than Selena's boyfriend Justin Bieber. The "Never Say Never" singer made a surprise on-stage performance when coming to her live concert in Costa Mesa, California last Sunday, but he chose to keep low profile when visiting her in Florida.

Dubbed "Own the Night", the tour will resume on July 30 at Ruth Eckerd Hall in Clearwater, Florida, and will run September 12 at Northwest Concert Center in Puyallup, Washington.
