Gwen Stefani and Gavin Rossdale were hand-in-hand for a walk around Primrose Hill earlier today, and later made their way to Heathrow. Gwen and Gavin met up in London, where Gavin hit the stage with Bush on three separate dates. He's been touring with his band for the last few months, but their busy traveling schedule will soon take Gavin closer to home. He has a show in Lake Tahoe on Saturday, which gives him a few days off to celebrate Thanksgiving with his wife and kids. The Stefani-Rossdales are just one of many celebrity families getting festive this Fall, including the Jolie-Pitts, Garner-Afflecks, and more.
