VANCOUVER -- It all came down to one night. After [article id="1712155"]months of hard work and preparation[/article], Selena Gomez finally unveiled her[article id="1712077"]Stars Dance Tour[/article] to an overflowing crowd of adoring fans at the Rogers Arena in Vancouver, British Columbia. And as the pop star herself has [article id="1712308"] mentioned [/article], she had a lot of prove -- both to herself and to her legion of fans.

When MTV News caught up with Gomez backstage ahead of the show, she said while there's a lot of pressure, she tries to stay focused. "There are so many things that are going through my head right before I step on stage, but I don't see anything except the stairs I'm about to walk up."

Selena Gomez kicked off the show with two songs from her previous albums, "Bang Bang Bang" and "Round & Round" set to all new choreography and midriff baring garb. [article id="1712308"]Gomez, who was nervous[/article] about perfecting her dance moves, didn't disappoint with her high-powered numbers as she commanded the stage like a seasoned pro.

She told us "once the first two songs are out of my system, I feel a little bit better, and then I'm able to let loose." And that's exactly what she did after performing the pulsating "B.E.A.T," showing off both her versatility and musical tastes by covering Australian rap sensation Iggy Azalea's "Work" complete with Selena rapping along to the track.

After a brief transition, Selena came back out to perform the title track off her Stars Dance album, followed by "Birthday." Unpredictably, the former Disney star then segue into a cover of Rihanna's 'Birthday Cake', a decidedly raunchier song with a meaning that may have been lost on many of the younger fans in the audience.

The crowd went nuts when Selena started belting out the first few notes of fan favorite "Love You Like a Love Song." As the crowd sang along, Selena ducked behind the curtains for a quick wardrobe change as the show set up for her mid set acoustic session.

As the arena lights dimmed, a concert video started playing on the screens. Footage of Selena walking the red carpet was overlaid with text and voices of the media commenting on her very public relationship and breakup with Justin Bieber. "I can't control what they think," she said. And with that Selena brought the house to a standstill with her emotional performance of "Love Will Remember," reportedly about her famous ex.

Afterwards, Selena offered the crowd one last cover song, explaining that she loved performing them because it gave her fans insight into her current inspirations. Gomez then launched into a breezy take on Lorde's "Royals" a version that matches, if not surpasses, the original (in this humble writers opinion) and the definite high point of the whole show.

Wearing a gold sequenced flapper dress, Selena showcased her polished dance moves, seductively swing around bright red rope for "Whiplash." She then got the crowd jumping up and down for a rousing run through "Naturally," "Save the Day" and "Undercover."

Of course, Selena had at least two more songs to perform before the night was over. As her fans cheered and screamed for an encore, Selena came out one last time to perform her hit single "Come and Get It." As the crowd danced along, Selena ended the night with her newest single, the EDM-infused "Slow Down" as the arena was showered with confetti and bright pink streamers.
