It's official, Iggy Azalea and Nick Young are engaged!

The NBA player's 30th birthday was all about the couple, as Swaggy P popped the question to his rapper girlfriend in front of family and friends.

What's even better is the whole thing was caught on video, so you can watch the very moment it all went down right here:

"It was a beautiful celebration for Nick with only his close friends and family. Nick completely surprised Iggy with the proposal. She was shocked and so excited and emotional at the same time," a source told E! News.

"Nick has known for a long time Iggy was the one for him, but he was just waiting on the perfect time to pop the question. They both have gotten very close these passed few months and he can't think of anyone else to spend his life with but her. One of the most important things about Iggy is the way she is to his son."

Both now on cloud nine, Iggy was quick to show off the huge diamond Nick had chosen for her:

The couple have been dating since September 2013, with Nick having a three-year-old son from a previous relationship.

Congrats guys!
