sunglasses shopping Sam Ronson hat lindsay lohan sweater jeans

We caught up with Samantha Ronson in Beverly Hills on Tuesday, where the singer was running errands with a smile.

We love that we can always count on Sam for her consistent style ... meaning a sweater, skinny jeans and a fedora.

Though -- Sam might not be as hipster as you'd think ... especially when it comes to the DJ's music taste. She Tweeted on Wednesday, "What defines me the most? The fact that I'm a PINK fan for life. #raiseyourglass"

Well said!
