Splitting: Shanna and Travis Barker?

Rumors of a possible split between Blink 182 drummer Travis Barker and his wife, Shanna, are heating up. The other night, the two showed up and partied separately at Hollywood hot spot Privilege. The rocker gladly signed autographs for fans, but when Shanna saw him taking a picture with an attractive female, sources say she stormed over, threw her drink on the young woman and her glass at her husband. Barker's rep, Dvora Vener, said, "No comment."
