London, Nov 12 : Celebrity chef Jamie Oliver, 33, has revealed that his pregnant wife Jools has developed an odd craving for hot water bottles.

The Naked Chef, as he is known, also revealed that Jools, 34, had a hunger for “retro” food from her childhood.

“Basically she’s an eating machine and I’m feeding her,” the Sun quoted him as telling US chat show host David Letterman.

“She’s gone back to retro food — fish paste, all that stuff from her childhood. She’s dipping bananas in vegemite.

“She goes to the hardware store and she gets rubber hot water bottles and she chews on them,” he added.

The couple, who already have daughters Poppy Honey, 6, and Daisy Boo, 5, are expecting their next baby in March, and Oliver revealed his odd efforts to ensure that Jools conceived a boy.

“I’ve tried everything — temperature, naked outside and a little run up,” he added. (ANI)
