Salma Hayek is never too busy to take time off work to play with her dear Valentina.

The 20-month-old celebuspawn stole the show as she played with mommy on the set of Grown Up yesterday afternoon (May 19) at Pilgrim Church in Southern Berkshire, MA.

The movie, which is directed by Dennis Dugan, co-stars Adam Sandler, Kevin James, Chris Rock, David Spade, Rob Schneider and Colin Quinn. The story centers on a bunch of guys and their respective spouses who return home for a July Fourth weekend after a 30-year absence.

Grown Ups will be shot mostly in Essex over the next two months. Yesterday, cast members were dressed in dark suits for a funeral scene. While somber for the cameras inside the church, the Hollywood pack flashed smiles, signed autographs and posed for pics for fans outside before heading off in a caravan of SUVs for a lunch break.
