'The Back-Up Plan' Trailer Hits the 'Net

Jennifer Lopez returns to the big screen for the first time since giving birth to twins. In The Back-Up Plan she stars as a single woman who undergoes artificial insemination. The same day she tests positive for pregnancy, she meet the man of her dreams (Alex O'Loughlin--what, Matthew McConaughey wasn't available?).

The Back-Up Plan hits theaters in March 2010, but you can see the trailer here.
