Out for a bout of retail therapy,  Lindsay Lohan was busy doing some shopping during Fashion Week in New York City on Thursday (September 10).

Changing in and out of two different outfits during the course of the day, the “Mean Girls” starlet hit up the local boutiques in search of a few new additions to her wardrobe.

Earlier this morning, LiLo was busily tweeting away – leaving an incoherent message directed at on/off lover, Samantha Ronson.

Upset over a recent tiff, LiLo wrote, “mwut82samantharonson can you make an attempt to not ruin ANYTHIzG positive that i have FINALLY deserved just to cry myself to sleep with your cheats, errors, and thank you…for being a friend before a sell-out……….the term “self out” was coined from ME and i gave them sooooooo much insight For their not only COMPLETE, BUT SUBSTANISAN ***FRIENDS*********** BUT YOU DID perform to her..you JUST told me that your friends are worth more than i am 2 your family & that i’m gross*thx.”
