Lindsay Lohan not only robbed the cradle with her latest romantic conquest -- she robbed the teen away from his girlfriend.

The 27-year-old actress is rumored to be carrying on a "secret romance" with 18-year-old Ralph Lauren model Morgan O’Connor for the past several months -- behind his girlfriend's back.

The young woman is said to have been "furious" with Morgan, who then tried to end his fling with the actress. He reportedly sent Linds a message while his girlfriend watched. The message read: "I can’t see you anymore. I have a very serious girlfriend who I love very much. I’m very sorry and honestly quite angry that I ever had anything with you, you are the epitome of trash and the world knows it. I just wanted to let you know to never contact me again and I never ever want to see you again."

Apparently it didn't work. Lindsay and the teen were spotted together just last week at Foxwoods Resort and Casino in Connecticut.

Making matters worse, Linds is said to have fallen off the wagon.
