Lauren Conrad  Derek Hough jeans drink Roosevelt dancing with the stars the hills

Lauren Conrad must be a big fan of Dancing With the Stars!

We caught up with the Hills hottie and her rumored new man, Derek Hough, as they tried to exit Hollywood's Roosevelt Hotel incognito -- they were partying at the nightclub inside!

The pair looked to be in a hurry, as Conrad, 25, was still holding her drink when Hough whisked her away in a Mercedes on Sunday night.

This sighting comes just after Hough, 26, addressed the recent hook-up reports as "rumors". The dancing pro told DWTS contestant Ricki Lake on Access Hollywood this weekend, “I don’t read these magazines. I hate to disappoint.”

Lake replied by telling Hough,“I think you guys would make a cute couple-if it were true.”

After looking at our pix, we definitely agree!
