Jennifer Lopez film the back up plan babies stroller

On set, that is.

La Lopez is still filming The Back-Up Plan in Manhattan and, in addition to some cute pix of her and Alex O'Loughlin pushing around fake babies in strollers, we ALSO got a coupla shots of the sexy stars smooching! Is it bad that we think this guy is hotter than her hubby?
