Gwen Stefani and No Doubt rocked Central Park this morning for a performance on Good Morning America. Gwen and the guys played their new single, "Settle Down," but before taking the stage they spoke about making their new record, Push and Shove, due out in September, and how things have changed for the band over the past 10 years. Gwen made reference to starting a family and talked about her boys, Kingston and Zuma. She said, "It was really hard to try to find the time [to write music] with those two little bunny rabbits that I made." It appears Gwen has no regrets about her labors, and added, "It was a real big effort, but totally worth it."
