Hollywood's hottest couple: Demi Lovato and Rihanna? That would be the case if the "Cool for the Summer" singer had her pick.

In an appearance on The Ellen Degeneres Show Monday (January 15), Lovato made her Hollywood crushes very clear through a game of "Who'd You Rather" (and one crush in particular). More than Harry Styles, Zac Efron, Milo Ventimiglia, Drake, Rita Ora, Chance The Rapper and Kristen Stewart (who also makes a strong showing), Lovato insists the "Kiss it Better" singer is who'd she get with, given the chance.

And Demi and Rihanna already have a bit of a history together — at least as far as social media is concerned. In 2011, they exchanged some serious adoration, with Rihanna posting "Demi Lovato goes so hard!!! She gangsta," before Demi replied "thank you!! Only cause I learn from the best!! Aka YOU!"

Demi's also tweeted that Rihanna is "#everythinggoals" and has covered Rihanna's "Stay."

In Lovato's 2017 YouTube documentary Simply Complicated, she explained that she and Wilmer Valderrama — her partner in her longest and highest-profile relationship — broke up in 2016 after six years together because she needed to experience life as a single woman.

The sparks never faded but there are issues that I haven’t conquered yet that I know I won’t conquer if I’m relying on somebody else to take care of the loneliness. I just wasn’t ready and there was so much in my life that I hadn’t explored yet," she said. "That was one of the reasons why we broke up because I’ve never been alone...It had nothing to do with falling out of love, we decided together we just probably are better as friends.
