Lindsay Lohan -- Giving New Roomie A Free Ride

Lindsay Lohan won't be living in her new Venice pad by herself -- TMZ has learned she's going to have a roommate ... and the girl will be staying there rent-free.

We're told LiLo's new roomie is a girl she met during her time at Betty Ford. According to our sources ... the girl has been sober longer than Lindsay has (FYI -- Lindsay celebrated four months of sobriety Friday).

Sources close to Lindsay tell us she feels it's important to Lindsay to surround herself with other sober people. We're told she's helping the cash-strapped girl out ... letting her live rent-free.

Seems Lindsay's first role post-rehab ... is that of a sugar mama.

Sam Ronson Accepting Lindsay Lohan Move-In?

Lindsay Lohan and Samantha Ronson were this close to becoming the new Hatfields and McCoys -- but TMZ has learned the former couple just struck a truce over LiLo's move to Sam's block in Venice, CA.

Sources extremely close to Lindsay tell us she spoke to Sam this week and explained she had "no idea" she was moving in to the condo directly next door ... and apologized for the surprise.

We're told Sam bought it -- go figure -- and they ended the chat on good terms.

Our source says Linds is expected to move in any day now and, "Neither of them are mad at each other and everything has been cleared up."
