Lindsay transition to the Lez Side is complete….

No men allowed! Lindsay Lohan barked at management for one Italian nightclub last month.

The troubled star is accused of putting a moratorium on peen after she banned males from Fiat Playa Discotheque in Sardinia, Italy during an appearance with galpal DJ, Samantha Ronson, on Aug. 18.

An onlooker tells Star Magazine: Management complied with her request — even making sure that only women were on staff — and the ladies spent the night dancing on banquettes.
