Gwen Stefani and Gavin Rossdale cheered on close friend Roger Federer at the Wimbledon Tennis Championships in London yesterday (06.07.08).

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.

The couple appeared tense throughout the highly stressful game, which was continually delayed by weather problems, and looked distraught when five-time Wimbledon champion Roger was beaten by his rival Rafael Nadal after four hours and 48 minutes of play.

Gwen and Gavin - who have a two-year-old son Kingston - have been close friends with the Swiss player for more than two years, and often see him on social occasions.

Last week, Roger was seen accompanying the couple and Kingston to London Zoo on his day off following his win against Dominik Hrbaty.

The No Doubt singer and former Bush frontman also cheered on Roger during the men's semi-final, which he won against Marat Safin.
