'Cause it's not enough for the Dancing With the Stars celebs to compete against each other, even the Results Show performers are now being ranked. A DWTS source told HollywoodLife that Selena Gomez —who performed "Hit the Lights" with her band on the Season 14, Week 5 Results Show — was one of the best musical guests ... ever?

"Selena was better than great," the source told HL. "She did what most artists don’t do on the show — sing live. Usually they either lip sync their performance or pre-tape multiple times before the live show to get it just right. But Selena really wanted to do it live and show what she could deliver."

Hmm. There have been a lot of great and maybe not-so-great DWTS performances over the years and as much as we love Selena, we can’t agree that she was that impressive.

One recent performer who stands out as being pretty darn adorable was Kelly Clarkson last season. The American Idol winner is no stranger to singing live herself — and after her DWTS Season 13 performance she even quipped that performing dance pros Tristan MacManus and Kym Johnson were distractingly hot on the dance floor. A singer with amazing pipes and equally amazing taste in dancing hotness — now that's a great musical guest!
