Lindsay -- Valentine's Day with Samantha Ronson

Lindsay Lohan will spend her Valentine's Day eating with a special friend ... Samantha Ronson ... but sources close to the actress tell us the plans are strictly platonic.



We're told Lindsay and Samantha will join a small group of friends for an intimate dinner party in Brentwood -- in honor of LiLo's entertainment manager's birthday.

One person from LiLo's inner circle tells us, "At the moment Lindsay and Samantha are just friends ... nothing more ... nothing less."
