When the Love Island Romeo tried to leave her suite at London's Sanderson Hotel in the early hours of Tuesday morning, Lindsay called some heavies and tried to stop him going.

Calum,25, insisted he had a plane to catch - he was due in Belfast later that day to switch on the Christmas lights at City Hall. But when he told Lindsay Lohan that he'd have to love her and leave her, she was having none of it.

Convinced he was off to meet someone else, the 20-year-old Herbie star called the hotel's security.

A spy reveals: "Staff thought Lindsay wanted them to get rid of Calum -they couldn't believe they wanted help to keep him there. She was going crazy, demanding to know why Calum had to leave. She wasn't listening when he told her he had to work.

"She was convinced he was going to meet another girl behind her back and was determined to stop him leaving.

"In the end they managed to calm her down but she went to bed angry, cursing Calum and saying she never wanted to see him again. He jumped into a car and sped off."

A pal of his tells says: "Calum's a legendary swordsman, but he can't keep up with Lindsay - she's wearing him out. He thinks she's a nice girl,but he's glad she's gone back home to LA."
