Christina Aguilera and Katie Holmes have signed to star together in a new movie. The pair will team up in family drama Humboldt Park, which will begin shooting in February - just weeks after Aguilera is due to give birth to her first child.

A source says, "(Holmes) is trying to prove she can do more than fluffy popcorn movies", and starring alongside Aguilera "shows she's willing to take risks."
