Jennifer Lopez hung with her family for a few hours yesterday on the LA set of HawthoRNe. Marc Anthony kept an eye on adventurous Max, while J Lo supervised Emme taking a few steps near the stairs — looks like the twins are displaying their very different personalities. The Lopez-Anthony clan returned to the West Coast after a few days in NYC, where Jennifer promoted her upcoming film The Back-up Plan on The Late Show and the morning circuit. Her interviews have ranged in topics from her career to her family, even revealing that Marc likes to sleep with her pregnancy pillow. Jennifer will be in red carpet mode for this evening's premiere with costar Alex O'Loughlin before it opens on Friday — we're also giving away her designer accessories from the film, enter to win them here!
