beverly hills denim blazer smile Samantha Ronson

Last night, a very chipper and smartly dressed Samantha Ronson was spotted at Chateau Marmont, and the DJ didn't have a whole lot to say to photogs, but she did deny proposing to Lindsay Lohan and buying her an engagement ring!

But what put Samantha in such a good mood? Was it seeing her fav X17 photographers or was it something Lindsay's been doing?
