The post contained an adorable snap of their son's tiny feet. 'Had a baby a week ago. Here are his feet,' she captioned the snap. The post did not reveal the child's name.

The announcement mirrors the post she made revealing the birth of their first child together, a daughter, three years ago.

Kate revealed the birth of her daughter on Instagram by sharing an artistic portrait of the tot's feet, along with the caption: 'We had a baby a couple weeks ago...Here are her feet.'

They welcomed their daughter in 2019 though they haven't revealed her name yet either. 

During a past interview with Shape Magazine, Kate expressed that she was 'very protective' of her marriage to Jamie, adding, 'I feel very proud to call Jamie my husband and to have made that commitment to him.'

Jamie was previously married to actress, Evan Rachel Wood, from 2012 until their divorce in 2014. He shares a nine-year-old son with Westworld actress, whom Kate has become stepmother to.
