Selena Gomez came to the premiere screening of her new film, 'Monte Carlo,' dressed to the nines -- but she wasn't without the support of her 'Baby' beau, Justin Bieber. The pair allegedly arrived separately, but we bet that was Biebs' idea, as to not take the spotlight away from his No. 1 girl.

The Disney star, an obvious guest of honor, being that she's the star of the flick, donned a light blue princess dress as she floated down the red carpet and into the theater. Separately, the 17-year-old pop icon maintained a more casual, dressed down sleek-in-black look, with red sneaker accents. While Gomez waved to photogs and took group photos with her co-stars, her boyish squeeze kept his hands in his pockets and didn't detract from her night -- a sign of true love and support!

In addition to Gomez, 'Monte Carlo' features the acting talents of Katie Cassidy, Leighton Meester, and 'Glee' heartthrob Cory Monteith. It hits theaters everywhere on July 1.
