It's A Zin! (NOW WITH VIDEO)

After an intimate lunch at Jerry's Deli (see video HERE), Britney Spears and Adnan Ghalib decided to eat in for a change.

We spotted the controversial couple at Ralph's last night stocking up on rice, chicken, chocolate, and wine (four mini-bottles of white Zinfandel - in bottles with twist-off caps).

Whatever Britney and Adnan had cooking, however, seemed to agree with Britney - once she made it past the paps, the pop princess appeared giddy, giggling and laughing all through the aisles!
