Jennifer Lopez brought a friend along Thursday when she headed out to run errands in LA. She's in California after spending the beginning of January in Miami, where she and Marc took in the final Dolphins game of the year and she fit in some shopping. Jennifer is currently in "hyper J Lo" mode promoting both her new album and The Back-Up Plan, though her recent interview with Elle ruffled a few feathers. She said she personally would never choose to use IVF as her character in the film does, and that apparently irritated some fertility advocates.
