Cullum reveals birth of baby Margot

Jazz star Jamie Cullum has become a father for a second time after wife Sophie Dahl gave birth to another daughter.

The pianist and singer broke the news to fans with a message on Twitter and said the baby, called Margot, had been born on Monday - just two days after her sister's birthday.

He said the couple were "completely thrilled".

Cullum and model-turned-writer and TV cook Dahl married in 2010 and their first child Lyra was born two years ago.

In his tweet he wrote: "On March 4th @sophiedahl gave birth to our second baby girl, Margot Cullum.

"She is healthy and gorgeous and we are completely thrilled."

Cullum recently signed a new record deal with Island Records and last month released his first new recording for three years as a free download, a cover of Cole Porter's Love For Sale which he recorded with rapper Roots Manuva.

He is expected to announce details of a new album soon.
