Diva: Selena Gomez dazzled in a showgirl-style number at her Boca Raton, Florida concert last night
Selena Gomez appeared to have taken tips from divas including Mariah Carey and Celine Dion as she took to the stage last night for her Florida concert.
The 19-year-old singer donned a Vegas showgirl-style sequinned dress for the We Own the Night show, but didn't quite manage to pull it off, and appeared old before her time in the outfit.
The plunging gown featured a sequinned corseted top and tasseled train, and is really aimed at women a few years older than Selena.

But Selena's fans certainly looked happy enough as the singer strutted her stuff on the stage at the Mizner Park Ampitheater and belted out some of her most famous songs.
The crowd at the concert would have been even more thrilled, had they known that Selena's boyfriend Justin Bieber was hiding out backstage.
The superstar made a surprise appearance during his girlfriend's debut concert last week, but preferred to keep a low profile tonight as he supported her on tour.

Justin watched from backstage with his friend, singer Sean Kingston, before darting out the back door before he could be spotted by the exuberant audience.
When he surprised Selena onstage last week he gave her a big hug to cheers from the audience, before singing an acoustic version of Justin Timberlake's hit song Cry Me A River and also performed his own hit, Favourite Girl.
Following the show, proud Justin later tweeted to his fans: 'Had a #greatnight and surprised the people. felt good to be on stage. nothing is changing that. #REAL. @selenagomez u did great tonight. proud of u.'

Earlier this week Selena was spotted enjoying a day off in Miami after performing in the city.
She was pictured relaxing on deck chairs by the pool of her hotel with a girlfriend.
The singer, who has been tipped for a role in the Sex And The City prequel, enjoyed her ocean view as she indulged in a spot of rest and relaxation ahead of her performance that night.
