I guess after seeing Lindsay Lohan on Ellen, Sam Ronson decided that she still really loves Lindsay Lohan and wants to work things out because her car was outside Lindsay Lohan's house all night and Sam Ronson didn't leave until 6 a.m.
So I don't know if this was just a booty call or a "I love you and let's work this out" moment, but I'm guessing that Sam Ronson probably felt like she was being used by Lindsay for a while there. Although that's kind of laughable because Sam wouldn't have made nearly as much money as she did had she not been with Lindsay.
Oh well, I guess all's well that ends well, huh?
