He became a dad for the fifth time last week and it's clear Jamie Oliver is already obsessed with his new baby boy. The celebrity chef has been spending as much time as possible with the little one, clocking up a series of cute milestones before he goes back to work.
One of the 'firsts' include baby's first bath time, and Jamie, 41, posted a seriously sweet photo of his son clutching his thumb in the tub.

Jamie wrote: "Sweet little fella, 8 days old, I can never get over how small they are, his hands are as big as my thumb… he wouldn't let go as he had his first proper bath… All good making the most of time with the family before I go back to work soon. Big love JO X."
He and wife Jools, 41, are also parents to Poppy Honey Rose, 14, Daisy Boo Pamela, 12, Petal Blossom Rainbow, six, and five-year-old Buddy Bear Maurice, and Jamie hacked her Instagram last week to praise her for her hard work.
