Gwen's Spicy Pregnancy Cravings!

Following a May 10 visit to the L.A. Zoo with 2-year old son Kingston, Gwen Stefani and hubby Gavin Rossdale penciled in a hot date night at West Hollywood's Marix Tex Mex restaurant.

On May 12, the couple dined on spicy Mexican, where sources say a pregnant Gwen couldn't get enough of the chips and hot salsa!

"Gwen's been carrying around a mini bottle of Tabasco in her purse," A friend of the star tells OK!. "She says she only has three categories of food she likes right now: hot, hotter and hottest!"

Gwen,38, and Gavin,40, didn't forget their little man at home. On their way out they grabbed an order of quesadillas and guacamole to go!
