Selena Gomez had a special guest, boyfriend Justin Bieber, along for a red carpet screening of her new movie Monte Carlo in NYC last night. The hot young couple didn't pose together on the red carpet, though Justin did admire Selena and her costars in the poster as he headed in to watch her latest big-screen venture. Selena sported a pretty blue gown for the event, and she met up with costar Katie Cassidy and Andie MacDowell for a few photos. Justin and Selena have managed to find time together despite their crazy schedules. Selena has both Monte Carlo and her new album, When the Sun Goes Down, coming out next week. Selena's career demands were partially responsible for her brief hospitalization earlier in the month, but she still has a big smile on her face whenever she steps out to greet her fans. Justin had his own crazy day in Manhattan yesterday, when things got a little too intense at his fragrance launch. Justin Bieber's bodyguards had a misunderstanding with a plain clothed cop. Thankfully, it all ended up OK, and the teen heartthrob was looking typically stylish while out to cheer on his real-life leading lady Selena.
