A shirtless Gavin Rossdale took a water break during a Bikram yoga class in LA yesterday. He's back in CA after spending the weekend in Florida, where he participated in a celebrity tennis tournament. Gavin unfortunately kept his impressive abs covered on the court, though, unlike during some of his previous matches. Gavin was alone on his trip, since his wife, Gwen Stefani, stayed home to play with Kingston and Zuma at a park. Gwen also had time to attend a baby shower for one of her No Doubt buddies, though bandmate Adrian Young missed out due to his joining other celebs in running the New York Marathon.
