Heavily pregnant pop star Gwen Stefani is back in Los Angeles as she eagerly awaits the arrival of her second child.

The singer, a study in maternity chic, was spotted leaving Italian restaurant Madeo with her husband Gavin Rossdale yesterday.

The pair touched down in the US after several weeks in London, where they were regularly spotted courtside at Wimbledon.

VIP guest: Gwen attended the Wimbledon final last week, but the five hour match left her looking weary

They cheered on their firm friend Roger Federer during his gladiatorial contest against Rafael Nadal in the final, and while tennis aficionado Gavin looked devastated at his friend's defeat, Gwen looked rather like she needed a little lie down.

Gavin Rossdale has admitted his American wife has had a difficult second pregnancy.

He said: 'It was difficult at first. Gwen really wasn't well.

'It was tough for her. She was really tired and suffering. I'm just trying to be right there for her. It's not easy to be pregnant.'

He added: 'I mean, isn't it enough that nature distorts your body and stretches and squashes your organs?

But she's blossoming now and she's in a great space.'

He also added that Miss Stefani felt the need to get her pre-pregnancy figure back as quickly as possible.

He said: 'She does feel pressure to lose the weight quickly. It's very hard because everyone is so judged.'
