Listen to Iggy Azalea on iHeartRadio

Iggy Azalea knows how to celebrate.

The rapper and her boyfriend, Nick Young of the Los Angeles Lakers, are both marking birthdays this week, and the stars are seen relaxing with each other on a boat in photos Azalea shared on Instagram (see below).

She wears a bikini in the shots.

Azalea has plenty of reasons to party these days, recently becoming the first artist to hold the top two spots on the Billboard 100 chart since The Beatles five decades ago.
