What up with THIS! Are Katie Holmes and Jamie Foxx dunzo?!

The actress/director dined with her All We Had co-star Michael Cavadias Friday night at The Local Peasant in Woodland Hills, just on the Valley side of LA. And she brought along daughter Suri ... and stayed out until 11pm!

Cavadias looked protective of Katie as photographers approached -- in fact, our snapper tells us: "Katie looked really comfortable with this guy. And he seemed comfortable with Suri -- like they'd hung out a lot. There is definitely a close friendship here, if not more."

So what about her hero, rumored-to-be-fiance Jamie Foxx? Well, we NEVER see the two together, but they've always kept their relationship on the DL. Was this dinner a meal between friends and co-stars or something more?

Katie's directing Michael in All We Had, a film about a mother and her 13-year-old daughter, living on the edge of poverty, who find an unlikely home amid the quirky residents of small town America. It will be Katie's directorial debut.
