Bush rocker Gavin Rossdale works up a sweat with a pal on tennis court in Los Angeles. The 54-year-old musician and occasional actor is looking stylish as he rocks a white headband and matching white Pepsi t-shirt. Rossdale, who was married to No Doubt frontwoman Gwen Stefani for 14 years, is apparently having difficulty with the bachelor life, having admitted he's, "not good at dating." Gavin went on to state in a previous interview, "I had a divorce, I had a long-term girlfriend, that went to s***. I don't have a girlfriend now. You get burned by that stuff."
