For the first time in three years, Jennifer Lopez has returned to film a movie. The pop star brought along her little son Max Anthony to the set, where the tiny tot showed off his newly-acquired walking skills.

The little man appears to have inherited his mother’s passion for fashion, wearing some expensive jeans, a studded belt, sneakers and a hoodie.

Interestingly enough, the premise of Jennifer’s film, The Back-Up Plan, is that her character conceives twins through artificial insemination and then meets the love of her life. Well isn’t she just the little method actress?
