Gwen Stefani and Gavin Rossdale cheered on close friend Roger Federer at the Wimbledon Tennis Championships in London yesterday.

The 38-year-old singer - who is heavily pregnant with her second child - looked stylish in a strapless red and black maxi dress teamed with aviator sunglasses and a leather jacket as she sat with Gavin alongside Roger's girlfriend Mirka Vavrinec in a private box.
