John Legend took a shot at some rival reality singing competition judges in an interview with E!. The entertainment network spoke with Legend and fellow ‘Duets’ judges Kelly Clarkson and Robin Thicke at the EW-ABC Upfront party. “You know it’s interesting. It should be very interesting. I don’t have much to say,” Legend said about ‘The X Factor’ adding Britney Spears and Demi Lovato as judges. “It’s interesting when people you know who are judging singing competitions when they aren’t really singers. It’s interesting.” Thicke and Clarkson had different views about the subject. Watch their comments below.

Update: John had this to say to his Twitter followers (@johnlegend):

Read my mentions today if you want some entertainment served with a side dish of crazy and a sprinkle of racism.

I’ve never heard Demi’s voice btw. Wasn’t referring to her.

Among some of those angry incoming Tweets:

Becc****ber1: @johnlegend LOL at you saying demi can’t sing? I mean who the fu** are you anyway? Thought so, irrelevant fu**.

Sab****yes: @johnlegend Who the fu** are you to say my Idol can’t sing?

Lo****ca: @johnlegend you’re a fu**ing moron, never speak ill of @ddlovato, she is the best, and your a fu**ing idiot.
