In Sunday's premiere episode of I Am Cait, fans see the candid moment the 17-year-old Keeping Up With the Kardashians star met Caitlyn.
Caitlyn is at home when she gets an unexpected FaceTime video chat from Kylie. Surprised to see Kylie for the first time as Cait, the 65-year-old says, "I don't want to scare you."
"You're not scaring me," Kylie says. "You look pretty!"
Flash forward: Kylie and Caitlyn finally get to meet each other face to face.
"I do want to meet her. It may be a little uncomfortable in the beginning but I think we're both ready," Kylie says before arriving to her dad's house.
"Hey, pretty!" Kylie smiles before giving Cait a giant hug.
"Hey, baby! I didn't know you were here!" a surprised Cait says. "You look so pretty," Kylie gushes.
But their in-person, girl-to-girl bonding doesn't stop there. Kylie even gives Cait flowing hair extensions!
