Lindsay LohanLindsay Lohan and close friend Courtenay Semel have reportedly ended their house-sharing arrangement after just over three months.

The two women are said to have moved in together late last year after Lindsay left rehab at the Cirque Lodge because they thought that sober Courtenay would be a good influence on the Mean Girls actress.

However a source has now told In Touch Weekly that while the two remain close, “they just can’t live together.”

Courtenay, the daughter of Yahoo! CEO Terry Semel, is said to like a tidy living environment while whirlwind clothes-fan Lindsay isn’t so organised: “Lindsay was always a mess. She had piles of clothes on the floor and on her bed all of the time.”

Another source added: “They decided to go in their separate ways before their differences ruined their friendship.”
