Justin Bieber and Selena Gomez kicked off their day with some shopping and were hand in hand last night on their way into dinner at LA's Maggiano's at The Grove. It was a special meal for the stars, as it was held to celebrate Justin's big 17th birthday. He and Selena got the party started on Sunday actually, as they both dressed up in coordinating black and red to show some PDA at Vanity Fair's post-Oscars party. The pair ranked among your favorite Academy Awards duos, and were even snapped sharing a particularly intimate moment. Justin tweeted before bed that the meal with Selena capped off a wonderful day. He wrote, "Great b-day. Flew in grandma and got my cake. Hung out with friends. Got surprised."
