"You know it's interesting. It should be very interesting. I don't have much to say," the Duets judge told E! News at the ABC upfront presentations this week. "It's interesting when people, you know, are judging singing competitions when they aren't really singers."
Ouch! Spears might be known for her dance moves, but Lovato has a set of pipes on her. Legend's co-star on the show, Robin Thicke, stuck up for the two pop princesses.
"Oh, come on, everything Britney does, she excels at," Thicke said. "Demi is a lovely young lady, and I'm sure they'll do nothing but make the show a lot more fun to watch."
"Obviously they are both performers so... I think that show really needs it I don't think everybody latched onto that show like they thought they would," she said.
"I'm excited for both of them. I'm a big fan of both of them. Both of those girls are super sweet," she added. "I think it's fun for them too to just be more out in the public eye again. I think those two are two you really want to root for and you really want them to succeed, so I think that's exciting."
