Scott Disick’s girlfriend has left her teenage years, celebrating her 20th birthday in Miami with the socialite in a big way.

Amelia Hamlin was spoiled by Disick, now 18 years her senior, who took her to Papi Steak restaurant over the weekend. He rolled out a massive five-tiered gilded cake, which matched the birthday girl’s outfit. The couple was first linked last October after he split from 22-year-old Sofia Richie, Page Six reported. They became Instagram-official in February, just in time for Valentine’s Day.

Per Page Six, the birthday caked was layered with edible photos of Hamlin in a thong and of her and Disick. Scott also gifted her a diamond-encrusted cross necklace, which moved her to tears, as shown in her Instagram post.

The birthday celebration comes nearly one month after she celebrated Scott’s 38th birthday by giving him a Harley.

She also posted a birthday tribute on her Instagram writing, “happy birthday my love. you light up my life, and make my world better. i can’t imagine what i would do without you. thank you for being you. the most caring, loving, special person on this planet. i’m so lucky. i’m so blessed to have met you. i love you 🤍🥺🤍”

Hamlin is the daughter of The Real Housewives of Beverly Hills‘ Lisa Rinna and Mad Men actor Harry Hamlin. Rinna said on Watch What Happens Live of the pair’s relationship, “It is what it is.”
