Amelia Gray Hamlin is 20! The model said goodbye to her teenage years on Sunday, and celebrated the night before with outings to Papi Steak restaurant and LIV nightclub in Miami, Florida.

By Hamlin’s side for the lavish evening was her boyfriend, Scott Disick, who gifted her with a diamond cross necklace that made her tear up. The model — who is the youngest daughter of Lisa Rinna and Harry Hamlin — shared that moment and more on her Instagram Story.

Hamlin first showed off her outfit for the night — a shimmery gold top and matching skirt — before sharing a photo of her and Disick holding hands. Fans got a glimpse at her giant cake and birthday celebrations, before Disick presented her with her birthday gift.

“I’m going to cry!” Hamlin is seen saying in the video, as Disick fastens the necklace around her neck. She gives her boyfriend a kiss and then wipes her tears away.
