The reality TV star will tie the knot to her long-term boyfriend Aaron Barham after he popped the question on a romantic carriage ride in New York`s Central Park. Her spokesman Max Clifford confirmed: "Stacey and Aaron are engaged and we`re all absolutely thrilled for them. "They`re a lovely genuine couple who get on so well. It`s a wonderful finale to what has been a tremendous year for her." The former `X Factor` contestant - who has three-year-old son Zac from a previous relationship - is expecting the couple`s first child in May. Stacey - who won jungle reality TV show `I`m A Celebrity ┘ Get Me Out of Here!` in 2010 - took to her twitter account to reveal Aaron had asked her for hand in marriage. She tweeted: "I can`t believe he`s finally asked me." But her photographer father David has ruled himself out of taking the official pictures on the brunette beauty`s big day. He said: "I will have father of the bride duties to carry out - so I will be taking a day off from work." In October, Stacey, 22, revealed the pair are "really excited" about expecting their first child together. She explained: "We are really excited. And I`m really looking forward to everything, knowing I am sharing it with the person I want to spend my life with. "I was nervous because we weren`t planning a child. But the first thing he did was smile. As soon as I saw that, I knew everything would be OK."
