I didn’t know she was pregnant - but here she is, spotted leaving a pre-natal yoga class on Saturday.  You can clearly see a baby bump, and why else would she be doing pre-natal yoga?  So who’s the baby daddy?

Eva Mendes will round out the cast for Frank Miller’s “The Spirit,” joining Scarlett Johansson, Samuel L. Jackson and Gabriel Macht.

Miller wrote the script and will direct the movie, which marks the start of a multipic pact under which Lionsgate and Odd Lot Entertainment will co-finance and co-produce together. Story centers on a rookie cop who fakes his own death so he can fight crime from the shadows.

Odd Lot’s Deborah Del Prete and Gigi Pritzker will produce along with Michael Uslan of Batfilm Prods; Batfilm co-founder Benjamin Melniker and Steve Maier are exec producers. Odd Lot’s Linda McDonough and Batfilm’s F.J. DeSanto co-produce.

Mendes was most recently in Columbia’s “Ghost Rider” and will be seen next in Columbia’s “We Own the Night.” She’s currently filming Picturehouse’s “The Women.”
