According to the Daily Mirror, Lohan and her boyfriend were partying at London’s Cliveden House, when another man caught her eye.
The star of the films Just My Luck and Freaky Friday, among others, was flirting with DJ Sam Young. A witness said, "She was all over him like a rash."
Lohan’s boyfriend, Harry Morton, 25, told her that she wasn’t paying enough attention to him, to which she responded by saying not to be so insecure. Morton wasn’t able to stop Lohan from her flirtatious behaviour. The witness added, "Then she began stroking his back and being really playful. At one stage, they even swapped numbers! "
