Ariana Grande's 'Thank U, Next' Director Reveals Which Exes Got a Heads Up and Why No OG 'Mean Girls' Made Cameos

Ariana Grande's viral song, "Thank U, Next," is still taking over our lives because we still have so many questions.

Thankfully, Hannah Lux Davis -- who directed the record-breaking music video -- answered some of those for us Monday night during a sit-down with Maria Menounos.

In the breakup anthem, Grande thanks specific exes for the "love," "patience" and "pain" they taught her. By name, she mentions Big Sean, Ricky Alvarez, Pete Davidson and Mac Miller.

Unfortunately, Mac passed away before Ariana dropped the single (and before she and Pete called off their whirlwind engagement), but Davis revealed she knows for certain that two of the other three ex-boyfriends mentioned in the song knew they'd be getting the shoutout.

"I know she gave Sean and Ricky a heads up," Davis told Menounos. "I can't speak on Pete. I don't know. I actually don't know."

"But if you read the 'Burn Book' -- or the 'Thank U, Next Book,' is what we're calling it -- it's all positive things," she added. "It's all good things."

Grande's rom-com-based video captured some of the most iconic scenes from "Legally Blonde," "13 Going on 30," "Bring It On" and "Mean Girls."

Some of the original actors and actresses (like Jonathan Bennett, who played "Aaron Samuels," and Jennifer Coolidge, who played nail technician "Paulette") made appearances, but none of the "Plastics" made the cut. Hannah says that was intentional.

"If we wanted to, we probably could've reached out to some of the original 'Mean Girls' girls, but we knew that we wanted to put [Ariana's] friends there," Davis explained. "So I think it was just being specific about who we wanted to reach out to. I think it was just enough."

"Kris Jenner made the perfect Ms. George, Regina George's mom," she added. "Everybody's flipping out over that cameo." Yes. Yes, we are.

While Davis maintains that Grande didn't "need the celebrity support," it certainly didn't hurt!
