Ariana Grande is the funniest pop star. She's proven it many times, but she solidified it with her Carpool Karaoke episode of The Late Late Show on Wednesday. (Grande has been killing it on the Late Late Show all week; on Monday's show she did a one-take Titanic musical.) I honestly forgot she hadn't done Carpool Karaoke with James Corden before, because she's perfect for it. (She did do it on the Apple Music version of the show with Seth MacFarlane, of all people.) Her powerful pipes get highlighted in such a stripped-down setting, plus she's a naturally funny person. This all makes for another great Carpool Karaoke.

In between renditions of her hits like "Dangerous Woman," "Side to Side" and "No Tears Left to Cry," Grande showed off her gift for impressions, doing a hilarious Celine Dion. But best of all was the moment she settled a rumor that claims that her diva behavior manifests as demanding to be being carried like a baby. She said that she posted the infamous photo because she thought it was cute that her tour manager was carrying her after she had shot a video in pointe shoes that left her feet bloody.

But Corden wasn't just going to let that go. They made a pit stop at Starbucks, and he had Grande hop on his back for a piggyback ride.

"Hello, I'm Ariana Grande. I must be carried," she said to the bewildered baristas.

"What size would you like?" Corden asked her.

"Oh, I'm gonna get a grande," she said, cracking up. "Gets them every time!" It got me. I sincerely love jokes that are so obvious you don't expect them.

Then they talked about how they each love Little Shop of Horrors and duetted on "Suddenly Seymour." It was delightful, if a bit of a rehash, since she did the same song with MacFarlane.

She didn't talk about her fiancé Pete Davidson at all, but Pete's got that covered. Also, she didn't address why she has that bandage on her hand, but she somehow injured it during filming.

The Late Late Show with James Corden airs weeknights at 12:37 a.m. ET on CBS.
