The Christmas present Iggy Azalea gave her longtime NBA star boyfriend Nick Young sparkled - because of all the chrome. The gift Young gave Azalea also sparkled - because of all the diamonds.

The "Black Widow" rapper was anxious to show the world what Young gave her, so she took to Instagram, E! Online reported. The Australian artist posted a close-up photo of a heart-shaped pendant covered in diamonds, and professed her undying love for Young by writing, "I love you indefinitely."

The glittery gift came just days after Azalea surprised her beau, who plays for the Los Angeles Lakers, with a way cool, vintage muscle car.  

At the time, he also took to Instagram to share photos of his gift from Azalea - a cobalt-blue Chevrolet convertible with lots of chrome and a massive red bow on top. 

The Grammy-nominated artist even left a note for Young that read, "A gift for Swaggy P from Iggy."

"My boo so dope!!!!" an understandably ecstatic Young captioned a collage of the new whip. "Thanks for the Christmas gift #loveyou You go girl!!!! Westside."

If diamonds are indeed a girl's best friend, then chrome galore could well be a boy's best friend. Just sayin'...
