Gwen Stefani and Gavin Rossdale’s son Kingston spent some quality time with his big sister! No, this 2-year-old wasn’t the outcome of an long ago tryst between Gwen and Gavin. This is Kingston and Zuma’s half sister, Daisy Lowe. She was born to the fashion designer Pearl Lowe after a one-night-stand with Gavin and was raised as her ex husband’s daughter until a paternity test proved that she was Gavin’s.
