That was fast!
An unnamed source tells Us Weekly, "Their work schedules and the distance just make dating impossible."
Too bad as the clean-cut former football player was reportedly a good influence on the fresh-out-of-rehab Lohan. Earlier, a source had told Us Weekly that he "won't drink around her. He's trying to keep her sober and on the straight and narrow."
But the two have been friends for several years and the unnamed source goes on to say that Matt "respects her sobriety and wishes her the absolute best. They will remain good friends."
Meanwhile, Lindsay just tweeted a picture of herself with the ultimate break-up food: ice cream!
Are you sad Matt and Lindsay called it quits? Who do you think he should date next? Tell us in the comments.
