Looks like Cash Warren is going to man up and marry the pregnant Jessica Alba. That is, if we take a slip of the tongue committed by one of her co-stars seriously.

SFGate reports that Doug Jones, who starred with Alba in “Fantastic Four”, referred to Warren as the actress’ fiancé, when asked over the weekend at the Jules Verne Adventure Film Festival about her pregnancy.

When asked about Alba’s baby news, Jones said, “Jessica and her fiance are wonderful, and they’re going to make the most beautiful babies ever.”

Apart from Jones’ big mouth, what furthered engagement speculations is that Alba was seen at an event last week wearing what looked like an eternity band on her wedding finger.

And here’s more about Alba’s pregnancy: Three magazines have already approached her and offered what could only be oodles of money for her to pose nude with a baby bump, just like Demi Moore and Christina Aguilera have done in the past. Fortunately, Alba passed. Nude preggo covers are so damn cliché.
