Kerry Katona and her fiancé George Kay reportedly had a huge bust-up at their joint hen and stag do.
The couple's pre-wedding party turned into a "disaster" after they had an argument at Hotel Verta in Battersea, London, on Friday,before Kerry allegedly refused to attend the bash on board a luxury cruise.
A source told the Daily Star Sunday newspaper: "The do was an absolute disaster. After the spa treatments Kerry and George had some sort of huge fight... she was crying and was really upset. All the guests got on the boat and were waiting for ages wondering what was going on. Then 45 minutes later they were told the party was being cancelled and to get off."
Kerry's bandmate and bridesmaid Liz McClarnon, 33, attempted settle the situation between the lovers but the 33-year-old star refused to leave her hotel room.
The source explained: "Liz and Karen Belton, a friend from home, went to try to talk her down but she refused... She wouldn't leave the room all night."
Meanwhile, the pair - who have four-month-old daughter Dylan-Jorge together - hit the headlines last month after George was detained under the Mental Health Act after taking a concoction of steroids,
sleeping pills and alcohol, which resulted in him running around their Oxfordshire home shouting that someone was trying to kill him and feeling like he was being "fried from the inside".
