Oliver and his wife, both 43, have been married for 18 years and the chef told Woman magazine his love for her had grown in that time.

London - He previously revealed that worries about social media had made him ban his children from posting selfies.

Now Jamie Oliver has admitted he uses a "spy app" to monitor the location of his teenage daughters.

The TV chef – father of Poppy, 16, Daisy 15, Petal, nine, Buddy, eight, and River, two – said the phone application enables him and his wife Jools to see exactly where their children are and the route they are taking.

"We use an app to keep track of our kids’ whereabouts," Oliver said in an interview.

"The older girls, Jools and I are all on an app called Life360, which means we can see exactly where everybody is and the route they’ve gone."

Outlining the benefits of the app, he said: "So if one of the girls says, 'I’m going to Camden Town' and I can see they’ve gone to Reading, then we have a problem. They can check on me, too, and see how fast I’m driving. It’s brilliant."

The free Life360 software is a family networking app which runs on mobile devices. It allows users to view family members on a map, communicate through the day, and receive live alerts when loved ones arrive at home, school or work.

Users can create "circles" with family or friends who also have the app on their phone. A user can turn off their location but other members of the circle are updated so they can make sure that member is safe.

Oliver and his wife, both 43, have been married for 18 years and the chef told Woman magazine his love for her had grown in that time.

"I like watching Jools get older," he said. "I love her more now than I ever have before.

"I feel like my love widens and I’m enjoying her evolving as a woman, growing older. I like it – her wrinkles have been earned.

"There has been a lot of chaos in the past 20 years, but she keeps the home very normal and stable, and that’s a lovely thing. We’re yin and yang – she’s very homey and family based and I grew up in a pub, I love going out and meeting people and that is not her idea of fun.

"She gets a lot more stressed than me and I calm her down and give her strength. But we come together over parenting; our approaches are very similar."
