We spotted Kelly Clarkson filming a video for her latest single "Dark Side" in Los Angeles over the weekend. The pop star wore a funky black, green and white dress with a sheer bodice. The gown showed off the pop star's curves.

Clarkson stars in a new singing competition premiering this summer on ABC. "Duets" will also include singers Robin Thicke, Lionel Richie and Jennifer Nettles as they hunt for musical proteges.

The former "American Idol" star just celebrated her 30th birthday on April 24.
