The working mom Jennifer Lopez is back to work after a long break. She is currently filming her new movie The Back-Up Plan, wherein she plays the role of a woman who is desperate to get pregnant. Through an artificial insemination, she actually became an expectant mother of a twin. Wearing her sexy mini dress and high-heeled boots in one of the scenes, Lopez still looks a hottie with her long legs shown. While filming, JLo’s one-year-old twin kids are with her under the care of her mom and a helper and watch their mom while glamorously doing her job.
