British pop star SOPHIE ELLIS-BEXTOR is desperate to quiz busy celebrity mum Gwen Stefani on how she balances her parenting duties with conquering the music world. The MURDER ON THE DANCE FLOOR singer is mother to two-year-old SONNY and is desperate to know how the American singer achieves success in parenting and pop. She says, "I'd love to sit down with Gwen Stefani and find out how she balances it all. Right now I know she takes her son, KINGSTON, round with her, but he's only a baby. "Gwen could probably have him sat down in a little chair next to her, but Sonny would be causing chaos running all over the place!"
