On her man's 38th birthday, Amelia Hamlin has Scott Disick very much on her mind.
In honor of the special occasion, the 19-year-old daughter of Real Housewives star Lisa Rinna and Harry Hamlin took to Instagram with a special message for the reality star she's been dating for about six months.
"Happy birthday my love. you light up my life, and make my world better," she wrote to the father of three with ex Kourtney Kardashian. "I can't imagine what i would do without you."
She continued to gush over Scott, writing, "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."
To conclude her birthday tribute—which includes the first photos of Scott she's posted on her Instagram profile—Amelia dropped the L-word. "I love you," she wrote. The teenage fashionista also shared an array of photos of their time spent together, including in a car, on a boat, on a plane and seemingly holding hands in bed.
The love-filled Instagram post was not the only way Amelia commemorated her boyfriend's birthday.
When his famous family and friends came together to celebrate his special day early, Scott revealed the expensive item Amelia gifted him: a Harley Davidson motorcycle.
Of course, this is hardly the first time she's shown her affections for the birthday star. In April, Amelia showed off a bracelet bearing his name on her wrist. The following month, a mirror selfie revealed she has a large sticker of Scott with a crown emoji on the back of her iPhone case.
With her 20th birthday approaching on June 13, fans will just have to wait and see what kind of lavish celebrations "Lord Disick" has in store for his special lady.
