According to The Sun, former Made In Chelsea star Millie demanded a divorce from rapper Pro Green during a drunken argument at a celeb party in Istanbul.
A fellow partygoer told them Millie, 24, screamed: "I want a divorce now! Give me a divorce!"
"Lots of people witnessed the row," another source told the newspaper. "Things escalated and she started screaming about a divorce at the top of her voice."
This isn't the first time their relationship has faced speculation. Last year Pro Green, real name Stephen Manderson, blasted breakdown rumours on Twitter, after Millie started using her maiden name on social media again.
He fumed: "Because we choose not to live out our relationship in the public eye wherever possible, and we don't show up to the opening of an envelope hence not giving you much to write about."
A source claimed that Millie and Pro are determined to make their marriage work, even if there are problems.
The insider said: "Stephen's lifestyle doesn't lend itself to marriage and she's very young. There are issues but they want to make a go go it and it will take a lot for her to divorce."
