Jessica Alba is expecting a baby, but don't expect the actress to look like it if she gets married!

Us Weekly reports in its new issue that Alba, 26, and boyfriend Cash Warren, 28, who split July 22 only to reunite in late August, currently don't have plans for a wedding. In fact, a source tells Us, "She doesn't want to be pregnant in a dress!"

But a wedding was on Alba's to-do list just before she broke up with Warren. "She wanted to get married, but Cash wasn't ready," says a source.

Nuptials or not, Alba's family is looking forward to her having a baby. "We're all thrilled for them," Alba's brother Josh tells Us.
