Gavin Rossdale and his son Kingston on Malibu beach. Malibu, California - 26.05.08

The former No Doubt star is expecting her second baby with the former Bush frontman this summer (08) - and Rossdale admits the first trimester was really hard on the star.

He says, "It was difficult at first. Gwen really wasn't well and it was tough for her. She was just really tired and was suffering, which is kind of sad in a way.

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

However Rossdale insists he is doing his best to help ease the singer's pregnancy woes.

He adds, "I'm just trying to be right there for her and trying to help her through it. It's not easy to be pregnant."

The couple married in 2002 and has a two-year-old son, Kingston.
