It was another day on the set of The Back-Up Plan for Jennifer Lopez. She’s here in these photos shooting scenes with actress Linda Lavin. The film is a romantic comedy about a woman who conceives twins through artificial insemination, only to meet the man of her dreams on the very same day.

Lopez can relate to the twins part of the story since she has some of her own. During yesterday’s shoot, her twins Max Anthony (in right arm) and Emme Anthony (in left arm) made an appearance on the set.

Okay, this is slightly off topic but, who thought Jennifer’s marriage to Marc Anthony would have lasted this long?
