Charlotte Church and fiance Gavin Henson are to split after five years together, according to a report in Britain.
The break-up comes six weeks after the couple announced their engagement in a glossy magazine.
The 24-year-old singer and Wales rugby star Henson, 28, have already agreed the details of their separation announcement, reported the News of the World newspaper.
Henson has told friends the relationship is over and is expected to move out of their £1.2 million ($2.5 million) home in Wales while Church stays there with their children, Ruby, 2, and 1-year-old Dexter.
The paper reported a source saying the relationship reached a crisis point when Henson flew to Norway in March to film a reality show. "At the time Charlotte was preparing her big comeback as a judge on BBC1's Over the Rainbow. She really needed him at home," said the insider.
When he returned, rows exploded. "In the end Gav was taking refuge on their yacht in Swansea because they were quarrelling too much in front of the kids.".
The celebrity couple, jointly worth an estimated £11 million, announced their engagement on April 20 in OK! magazine.
Henson flew Church in a helicopter from their 9ha home in Saint Brides Major, Mid Glamorgan, to a hotel in Truro, Cornwall, to pop the question.
He got down on one knee and presented the singer with a two-carat, heart-shaped diamond ring for her 24th birthday on February 21.
Church told the magazine: "He started saying: 'We've been together five years, we've had good times and hard times but it's mostly been good. I think we are meant to be together for the rest of our lives.'
"I was a bit confused. He never says anything like that. Then he went down on one knee and said: 'Will you marry me?' I was absolutely joyous. I was so pleased."
