Lindsay Lohan and Samantha Ronson: Not Having (Calum) Best of Time

Awful pun alert: For Lindsay Lohan and Samantha Ronson last night, it wasn't the Calum Best of times.

According to Great Britain's The Sun, the most famous pair of partying lesbians on the planet got into a fight because Lohan was dancing with her ex-boyfriend.

A source said Lindsay "had tears in her eyes as she left" London club Boujis on her own.

Lohan and Best - who once described the Firecrotch Queen as being "dynamite" in bed - dated for several weeks last year. Soon after, Lindsay entered rehab and started having sex with women.

Tough break, Calum.
