Stacey Solomon has separated from her partner of four years, Aaron Barnham.
Stacey and Aaron got engaged in December 2011, and welcomed their first child together - their son Leighton - in May 2012.
The former X Factor singer, 24, is also mum to Zachary, six, her son from a previous relationship.
A spokesperson for Stacey confirmed the news with the message: "It's with regret that I can confirm that Stacey's relationship with Aaron has unfortunately come to an end.
"Her priority is her two children. She thanks her fans for their support at this time."
In an interview last year, Stacey told New magazine that she wanted to expand her family in the future, saying: "I'd like a girl. I'l like to have someone who'll always need me for something!"
Speaking to Parentdish in 2011, Stacey said she wanted a large family, but when the time was right. She told us: "I want a massive family, but I'm in no rush - give me a few years yet!"
