Myleene Klass gave birth to a baby girl yesterday, three weeks earlier than planned.

Myleene was on her way home from presenting The One Show went she went into labour.

Her spokesperson confirmed: “Myleene presented The One Show and felt a bit weird on the way home. She went to the hospital to get checked out and they told her she was in labour.”

“Myleene had a problem-free labour, and mother and baby are doing well. She and fiancé Graham are ecstatic.”

Baby Ava was born at 1.43pm yesterday and weighed in at 5lbs 9oz.

She had been due to arrive on the 7th of September but Myleene had previously revealed that doctors weren’t convinced about the date: “Everyone has a different date for the arrival. But I’m not going to get wound up about it.”

A friend of the couple told the Mirror yesterday: “It was all very unexpected. They were nervous but the birth couldn’t have gone better. They haven’t stopped smiling since Ava was born.”
