The 28-year-old TV star has posted a black-and-white photograph on her Instagram account of her leaving the hospital with her fiance Ryan Thomas and their baby boy.

Lucy - who gave birth to her son Roman on March 7 - captioned the snap: "This was one of the most surreal moments of my life that I will cherish forever. When we left hospital to head home with our new baby.

"On our way home I've never seen Ryan drive so slowly & sensibly in my life [laughing emoji] I sat in the back watching my beautiful boy (sic)"

Lucy gave birth to her baby boy shortly after Ryan revealed that brunette beauty "threw up" everywhere after accepting his marriage proposal.

He said: "For some reason we thought it would be a great idea to go to a nightclub. We got there and immediately regretted it so walked back out again and went to a beach bar. And then she threw up!"

Lucy added: "I don't know if it was the excitement of the champagne but I threw up as soon as we got to the bar!

"Poor Ryan had to hold my hair back. I'd only had a couple of drinks so I think it was because I was feeling so overwhelmed!"

Ryan also revealed that his wife-to-be kept him "waiting for ages" because she was in "total shock" with the proposal.

He recalled: "She kept me waiting for ages before she said yes! I kept having to repeat the question as she wasn't answering me.

"She was just sat there with her hands over her mouth squealing, 'Oh my God. You're kidding me? Oh my God.'"
