Jlo is glad she isn't a single mum

Jennifer Lopez was really acting in her new movie "The Back-Up Plan" because she could never imagine herself as a single mom.

The diva plays an unlucky-in-love single, who decides to have a child alone - and then falls for Mr. Right - in the romantic comedy.

She admits playing a mom-to-be was easy because she could still remember what it was like to be pregnant in real life, but she couldn't imagine having kids without a partner, like her character.

Woe thanks for ruining it for single mums jen!
