Gavin Rossdale may be a Grammy-nominated rockstar, but he's not afraid to admit that he's no longer the best musician in his household. "What happens with me now in my house [is] they'll play their songs - what they're doing," Rossdale, 59, exclusively told Us Weekly of his children on Monday, July 21, in celebration of I Beat Loneliness, BUSH's 10th studio album, released July 18. "Kingston will do that - play an amazing song," he continued. "Zuma has begun recording - he's out of control. I'm not even the best singer in my house anymore. It's super annoying.
