Susie Wollf expecting her first child

Former Williams test driver Susie Wolff is expecting her first child with husband Toto Wolff.

The Mercedes motorsport boss confirmed the news in the paddock at Austin, telling reporters: "Yes, it's true".

"My wife Susie is pregnant and we are expecting our baby in April," he revealed. "Whether it is a boy or a girl, the main thing is that it is healthy."

Susie Wolff, who previously raced in DTM, now serves as a pundit for Channel 4 in the UK, but she has missed a number of races recently and she will not be attending the United States or Mexico Grands Prix either.
