The former 'EastEnders' star, 41, gave birth to a little boy named Ezra Cillian - her third child with husband Phil Davies - in early March and she has now opened up about becoming a mum again revealing she's tired but very happy since her son arrived.

She told OK! magazine: "It’s so all-consuming. You’re so full of love – and knackered! – but you get those moments when Ezra does what looks like a smile and you forget that you’ve been up since 3am. It’s just lovely."

Kellie - who is also mum to seven-year-old twins Pearl and Louie - revealed Ezra was born on World Book Day on March 2 so the family prepared him a special outfit to celebrate.

She explained: "He was born on World Book Day. We knew he was going to be born on that day, so we put him in a little Harry Potter outfit. Louie was dressed as Harry Potter and said: 'Mummy, can we get the baby a Harry Potter outfit, too?'"

The actress - who played Carly Wicks on BBC soap 'EastEnders' from 2006 until 2012 - previously revealed her pregnancy came as a total surprise because she mistook her symptoms for heat exhaustion.

She told OK!: "I was literally on my hands and knees feeling horrendous and the on set medic called John, said, ‘Are you sure you’re not pregnant?’. I was like, ‘Oh no, I’m hardly seeing my husband! It’s just this heat.’ Kellie added she was eventually persuaded by John to do a test and was greeted with a "really lovely surprise." She added: "Then I was being sick for a couple of weeks and he said, ‘Go and get a pregnancy test’, so I did. It came back positive straightaway. I was like, ‘Oh my God, John was right!’ It was a really lovely surprise. I feel very lucky.”
