Celebrity Gwen Stefani Stuns on Red Carpet Before Gavin Rossdale Puts Wedding Ring Front and Center The divorced singers make separate solo outings after claims that he cheated with former nanny By Nick Maslow Nick Maslow Instagram Twitter Senior News Editor, PEOPLE People Editorial Guidelines Published on November 16, 2015 07:45 PM Share Tweet Pin Email Photo: JB Lacroix/WireImage; FameFlynet/AKM-GSI Gavin Rossdale‘s wedding ring continues to outlast his marriage to Gwen Stefani. On Sunday, Rossdale, 50, stepped out in Los Angeles wearing a silver design on his ring finger. The Bush rocker kept it casual for the outing, tying his long locks back and slipping into a grey sweatshirt, white t-shirt and drop-crotch pants. One day before, Stefani, 46, dazzled on the red carpet at the Baby2Baby Gala benefiting disadvantaged children. Donning a one-shoulder dress featuring cutout flowers that revealed a nude underlay, the singer soon made her way inside the big event, where she caught up with Kourtney Kardashian. Stefani and Rossdale have faced increased speculation about their divorce in recent weeks. After a source confirmed to PEOPLE that the “Used to Love You” singer has moved on with fellow Voice judge Blake Shelton, reports claimed Rossdale cheated on Stefani during their marriage with the former nanny for their three children, Kingston, 9, Zuma, 7, and Apollo, 20 months. A source close to Rossdale shut down a story purporting that he cheated with the nanny while Stefani was in the hospital after welcoming Apollo, saying the report “is 100-percent untrue. It’s bulls—.”
