LOS ANGELES, CA  [Tuesday Dec.19.2006]  /WMQT.com/ -- Kelly Clarkson may be at the the top of Santa's 'naughty' list this Christmas.

The American Idol winner has taken part in a nasty prank along with former Evanescence member Ben Moody and the gang over at NRG Studios, where Clarkson was recording at the time.

The studio had received a plaque in honor of Evanescence, but Moody's name had specifically been ommitted. As an act of revenge, the group went over to Evanescence singer Amy Lee's house to 'TP' it. The incident was all caught on tape, and can now be seen on YouTube under the title "At The Studio - Kelly Parts."

However, the current video is the edited version -- an earlier segment had been posted that featured Clarkson hanging with Matt Zane and Ron Jeremy of the adult film world. That piece was shown on E! News "Daily 10."
