Photos of Jennifer Lopez Filming The Back-Up Plan in Pasadena

Jennifer Is Back to Working Around the Clock

Jennifer Lopez glowed as she got touched up on the set of The Back-Up Plan in Pasadena on Thursday night. She was seen rehearsing her lines earlier in the day and slipped into a cocktail dress for filming alongside her costar Alex O'Loughlin. Jennifer didn't have any visitors this time around but maybe the next time Marc stops by he'll give the twins a chance to see their mom in action.
