Do they make divas like they used to? Late-night host James Corden said they didn’t, but that was before he met Demi Lovato.

Corden opened his show saying how he found his new favorite radio station, which only plays the tunes from divas such as Tina Turner and Cher.

“They don’t make them like that anymore, do they?” he proposed. “Divas back then were just better than divas are today. They didn’t have Instagram. they just had sass, voice, songs.”

Modern-day diva Demi Lovato wasn’t having any of that, so she challenged Corden to a diva-off. Lovato brought out an a cappella group — Level — for the occasion, which meant Corden couldn’t refuse the challenge.

“I got hits from before you were born,” Corden said.

“And, um, I got hits that are my own,” Lovato responded.

Lovato began performing Adele’s “Rolling in the Deep,” which Corden followed up with Tina Turner’s “River Deep, Mountain High.” They then moved into Aretha Franklin’s “Respect” and Katy Perry’s “Roar” (you can guess who covered which tune).

However, Lovato was able to pull out a win when she countered with her own track, “Heart Attack” and then dropped the mic.

Is it cheating if you sing a song that you wrote when the other person doesn’t have any? It doesn’t matter. Lovato proved that modern-day divas are just as cool as the classic ones, all while suggesting that maybe there is a way for both to exist together.

Corden has made a name for himself as the late-night host that can belt out a tune thanks to Carpool Karaoke and his countless musical sketches, but as much as he tried, he couldn’t compete with Lovato. At least they found a way to work together. They had to remain civil for when Lovato came on for an interview later.

Watch the full diva-off above.

Winner: NBC
While CBS claimed the traditional fall and spring television season -- thanks in large part to Super Bowl 50 -- it was another 52-week TV ratings win for NBC. Obviously the Summer Olympics didn't hurt, and NBC is poised to keep it up, thanks to the huge launch of "This Is Us," the fall's biggest freshman show.

Winner: HBO
It was another great Emmys season for HBO, which swept the best series categories with "Game of Thrones" (Drama) and "Veep" (Comedy). Plus, love or it not, the launch of new series "Westworld" has kept the pay-TV channel in the conversation through December.

Loser: NFL football
Thus far, this has mostly been an NFL season to forget. Primetime games have been particularly bad, and most "Thursday Night Football" match-ups haven't even been watchable. That, plus perhaps a few too many rules changes have sent NFL TV ratings in the wrong direction -- just hope for a memorable playoffs at this point.

Winner: "Grease: Live"
Just when we thought live TV musicals couldn't get any more fun than "The Wiz Live," they definitely did. Fox's "Grease: Live" was simply awesome, incorporating crowds, weather and a giant campus to play with. NBC's "Hairspray Live!" paled in comparison.

Loser: Thomas Gibson
Ain't life a kick in the shins sometimes? Thomas Gibson literally lost something this year -- his longtime gig on CBS hit "Criminal Minds." The parting of ways wasn't his choice, and it all came about after a run-in with a producer. And by "run-in," we mean Gibson's foot into the other guy's leg.

Winner: Cable news
Election season is always a boon to cable news channels. Throw in Donald Trump, and Nielsen can't count the viewers quickly enough. Mix in an actual Trump victory, and the TV ratings will carry on through the holidays.

Loser: Billy Bush
OK, so it wasn't just Thomas Gibson who lost a gig this year -- and Billy Bush's booting by NBC's "Today" show was even more high-profile. In case you somehow forget, Bush was the laughing hyena in Donald Trump's "grab 'em by the p---y" conversation.

Winner: FX miniseries
Here's how good FX's "The People v. O.J. Simpson" was -- it completely overshadowed an excellent "Fargo" Season 2 (ignoring that weird spaceship stuff).

Loser: Viacom
Did you not see this one coming? What a disaster 2016 has been for Viacom. Most of the year saw Sumner Redstone and Philippe Dauman squabbling through the media and court system. Eventually Dauman was bought out and replaced -- twice. Here's to 2017.

Winner: James Corden
This has undoubtedly been the year of James Corden. The CBS "Late Late Show" host has gone from a relative unknown to one of TV's biggest darlings. The internet loves the "Carpool Karaoke" driver too, and the multi-hyphenate has already graduated from the Tonys to the Grammys.

Loser: Roger Ailes
After a flurry of sexual harassment allegations, Fox News boss Roger Ailes was handed a giant check and his walking papers. Can one still be a loser if given $40 million to retire? In this case, yes.

Winner: Netflix
Let's end this on a happy note, shall we? Netflix just keeps killing it, and 2016 has been no exception. The streaming giant started the year with some strong "Making a Murderer" carryover. It then added a bunch of promising series to its original lineup, like "Fuller House," "Black Mirror," "Luke Cage" and "Stranger Things."
