The 40-year-old chef and wife Jools - who already have daughters Poppy, 13, Daisy, 12, and Petal, six, and son Buddy, five, together - stepped out at the 'Eddie the Eagle' premiere in London tonight (17.03.16), with the 41-year-old beauty's growing bump clearly on show.

The couple will reportedly welcome the baby into the world this summer.

A source told the MailOnline website: "Jools is radiant and blooming for the fifth time. The baby is expected in August."

Jools admitted in 2012 she was keen to have another baby but the pair planned to wait.

She said: "I want a fifth, but I know it would be wrong. I never get any time to spend with Jamie as it is. He has said give it a couple of years, then maybe we can think about it."

And two years later, her spouse admitted he wasn't as keen on the idea of a fifth baby.

He said: "She is 40 in about 10 days and I took her out and she goes, 'OK are we going to have another kid then?' I said, 'You what?'.

"The woman wants another baby. So watch this space. But with all the power in my body we are not having another baby."

However, a few months later the designer appeared to have changed her spouse's mind.

She said: "There's this Moses basket I designed that I haven't been able to test personally yet. It would be nice to put it to use."
