Who's the latest celebrity fan of "The Bachelorette"?

It's none other than Justin Bieber.

On June 25, the Biebs took to Instagram to proclaim his love for the ABC dating competition show -- and also to support Season 12's fan-favorite villain, Chad Johnson.

Justin posted a clip of himself watching a scene from the show in which Chad, a former Marine-turned-luxury real estate agent, is arguing with fellow contestant (and Marine) Alex Woytkiw during the villain's final two-on-one date with Bachelorette JoJo Fletcher.

(Justin's clearly a little behind in his "Bachelorette" viewing: JoJo gave aggressive, lunchmeat-scarfing Chad the boot on the June 7 episode.)

"Have a glass of milk, man, like, chill out," Chad tells Alex, who responds with, "Don't like milk."

Chad's comeback? "You should -- milk's delicious!"

The Biebs' response to the quip is equally amazing.

"Good point chad milk is delicious," Justin wrote on Instagram alongside the video clip, in which you can hear him laughing after Chad delivers his milk endorsement.

"And yeah I watch the bachelorette don't judge me," Justin added.

There's no shame in loving "The Bachelorette," Justin!

Chad, meanwhile, took a break from posting shirtless Instagram selfies that show off his buff bod to tweet his joy at being backed up by the pop star.

"Hell ya Justin.. Tag me on that Insta, brah lol @justinbieber #TheBachelorette," Chad tweeted the same day.

Chad returns to television later this summer on the next installment of "Bachelor in Paradise."

Now we just need to know what the "Got Milk?" campaign has to say about all this...
