Jennifer Lopez had her husband, Marc Anthony, by her side for last night's premiere of The Back-up Plan in LA. Her onscreen love interest, Alex O'Loughlin, was also there to pose for photos with J Lo, and her pal Heidi Klum took a break from doing her own press to hit the red carpet too. Jennifer has been hard at work promoting the movie over the last few weeks with a screening in Miami and a press tour in NYC, and we'll see if her efforts pay off at the box office this weekend. She spent a chunk of last Summer filming the project in the Big Apple, and now you can get a piece of her character Zoe's wardrobe — make sure to enter CelebStyle's contest to win accessories J Lo wore on the set!
