"They don't make 'em like that anymore, do they?'" he said.
Lovato, 24, wasn't willing to let that comment slide, taking the stage and proposing an epic riff-off.
On Wednesday evening's Late Late Show, the "Confident" hitmaker ready to take host James Corden to task when he claimed that there are no present-day starlets who can hold a match to the classic musical greats like Aretha Franklin and Cher. "Wow, that was terrible, just really awful, bad", she fired back.
Arsenal should do everything to keep Sanchez, says Campbell
The likes of Robin van Persie, Samir Nasri , Emmanuel Adebayor and Cesc Fabregas all left the club and Sanchez could follow them.
To bring the house down, Lovato sang her own hit, "Heart Attack", which prompted Corden to declare her the victor. I mean she and James did sing "I will Survive" at the end of the Diva Riff-off! "They didn't have Instagram, they just have sass, voice, songs", he said. "You're the best damn diva I've ever seen", she told him. She performed both Adele's Rolling in the Deep and Katy Perry's Roar, and did both divas total justice!This was a much better performance than when she appeared on "EW" on the Late Night Show with Jimmy Fallon. She did a mic drop after finishing her own song "Heart Attack" and demanded Corden pick it up.
As a bonus, Corden also showed some video of Lovato slapping an armbar on her boyfriend, MMA fighter Guilherme Vasconcelos, during a wicked jujitsu workout.
