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.

Gwen Stefani "never wants to stop working".

The 38-year-old singer - who is currently expecting her second child with husband Gavin Rossdale - insists she is too driven and motivated to give up her career and become a stay-at-home mother.

Gwen Stefani says being an overweight child has made her weight conscious.

The No Doubt singer says she struggled with her weight when she was growing up and insists she has to work hard to maintain her figure.

Gwen Stefani is letting two-year-old son Kingston name her unborn baby.

The No Doubt singer - who is expecting her second child with husband Gavin Rossdale - doesn't want Kingston to feel left out when his sibling arrives and is eager to get him involved.

Gavin Rossdale says his wife Gwen Stefani finds pregnancy "tough."

Gwen, who already has a two-year-old son Kingston with the rocker, has been feeling very tired as she copes with the demands of expecting her second child.
