Iggy Azalea and Los Angeles Lakers star, Nick Young are engaged.

Nick popped the question Monday night at his 30th birthday party, and then slipped a $500,000 rock on Iggy's finger.

It's got an 8.15-carat yellow center stone with 2.28 carats of smaller white diamonds, set onto 18-karat white gold.

They've been together about a year and a half.
