We're happy they figured things out!

Miley Cyrus surprised Hailey Baldwin and Kendall Jenner on Carpool Karaoke, and the singer admitted that she wasn't always the nicest person to The Biebs' wife.

“I would be evil to her. She would try to play with us, like me and Alaia, and then we would lock her out of the room and be evil," the "Wrecking Ball" songstress revealed about her long relationship with Baldwin and her sister.

“I had to. It made you who you are, you know? It made you stronger. Now you can always take like … the trolls and s–t. ‘Cause I was such a troll," she added.

The blonde bombshell doesn't carry any resentment, though!

"Miley was the biggest troll to me. She prepared me for this industry!” she joked.

We had no idea these two had such a long history!
