Jennifer Lopez Gets Back-Up Support

Jennifer Lopez walks to the set of her new romantic comedy, The Back-Up Plan, on Thursday (May 14) in Pasadena, Calif.

The 39-year-old’s daughter Emme had a medical scare at just 3-months-old. Jennifer told E!, “We both got very nervous, very very nervous, and I just remember my heart sinking to my feet. I looked at [my husband Marc Anthony] and I said, ‘You know if anything happens, I’m not going to be OK, you know that, right?’ Luckily, in the end, she turned out fine.”
