Kingston Rossdale is only 2 years old, but he is ready to rock! According to his proud papa, the spawn of Gwen Stefani and Gavin Rossdale is showing early signs of being a superstar. “It’s pretty fun when he comes to work with me. He likes my guitar peddles, and he likes speaking in the microphone,” Gavin told In Touch at his T-Mobile Sidekick Mobile concert in Hollywood on April 9. And though he hit the drums and keyboard in a recent studio session, little Kingston should look for for another way to increase his allowance. “I didn’t pay him!” daddy Gavin laughed.
