It's all about Ariana! Ms. Grande has broken the Beatles' record of being the only band to ever hold the top three positions on the Billboard Hot 100 and Arianators are LIVING for this news!

Ariana spoke to James Corden last night on the Late Show about this amazing career milestone and about being lonely and focusing on work since calling off her engagement to former fiance Pete Davidson.

For the time being, Ari's been in a relationship with "7 Rings," "Thank U, Next," and "Break Up With Your Girlfriend, I'm Bored" -- her three singles at the top of the chart this week. Other than that, her love life's been a little dry, she admits.

And she says of her record-breaking record, "I think it's so funny. I thought it was hilarious. When I woke up, I thought it was like an edit, like that my fans made, 'cause you know, they're like insane people that I love. But I thought it was a joke ... I was like: "I'm so sorry, this is so weird and crazy." I'll take a break after this. I'll go away for a little, I promise."

We DEFINITELY don't want her to go away! But Ari said she's "tired of her voice coming out." JK -- she also told Corden she was going to celebrate the news by hitting the studio -- so we won't be missing her voice any time soon, thank god!

After the interview, Grande surprised "World's Best" singers the TNT Boys -- a Filipino child singing group that's become a hit on the talent competition show that Corden hosts and it was SO cute! Roll tape! ...
