Stacey Solomon has split from her fiancé Aaron Barnham, her spokesperson has confirmed.
The couple had been together for four years, and got engaged in December 2011.
"It's with regret that I can confirm that Stacey's relationship with Aaron has unfortunately come to an end," the 24-year-old's rep said. "Her priority is her two children. She thanks her fans for their support at this time."
Stacey and Aaron started dating in 2009, and shorty after getting engaged announced that they were expecting their first baby together.
Son Leighton was born in May 2012 — a little brother for Stacey's son Zachary, six, from a previous relationship.
In an interview last summer, the 2010 I'm A Celebrity... winner admitted she would love to expand her brood further and have a little girl.
"If I'd had a girl the second time round, I think I'd have said no (to having another baby)," see told new! magazine. "I'd like a girl. I'l like to have someone who'll always need me for something!"
Stacey also admitted that she and Aaron were yet to start planning their wedding.
"That is the last thing on our list of things to do," she said. "I reckon it will be a while, unfortunately. There's never a good time to get married, is there? We might just elope.
"I might get married in Cornwall or somewhere on the coast. We have looked at a few places abroad, too. Argh! I don't know anything!"
