Lauren Conrad's Crown Clubbing

Lauren Conrad parties all night long at Crown Club in Hollywood on Wednesday night.

MTV tells us a few tidbits about the upcoming season of The Hills: “Well, despite what the tabloids would have you believe, there’s a whole lot more to Season 4 than a so-called feud between Audrina and Lo. From spontaneously appearing siblings (i.e. Heidi‘s never -before-mentioned sister!) to Stephanie‘s secret romantic foibles to Lauren‘s private jet-owning new love interest, this season has more drama than a Jerry Springer marathon.”

Check out a sneak peek trailer at season four of The Hills.

The Hills premieres this season on August 18 at 10pm ET/PT.
