The figures from the Marriage Foundation found 50% of all celeb marriages which started between 2001 and 2010 had broken up by the end of 2014.
That compares to just 26% of ordinary couples.
Marriage Foundation's analysis of 488 famous couples also found they are six times more likely to divorce in their first year of marriage than average couples.
Harry Benson, the Foundation's Research Director and a Christian, said that a culture which encourages self-importance could be the reason for the figures.
He told Premier: "Isn't it deeply ironic? That here we are, some of the richest people of society and certainly some of the best known... and yet they're the most needy.
"You can imagine how tough it must be when you're presented with all this tremendous temptation and told that you're the centre of the universe, and yet actually to make a relationship work the big secret is actually to put the other person first.
"I have an enormous amount of compassion for celebs. I don't want celebrities to fail, I want them to succeed, they're our role models. I want them to be as successful as possible."
