Iggy Azalea has reportedly moved in with her boyfriend Nick Young.

The Australian rapper - who started dating the LA Lakers basketball player just over a year ago - decided to take their romance to the next level and has moved her things into his mansion and he has even started calling her ''Mrs''.

A source told US OK! magazine: ''She's head over heels, and everyone says what a great match they are. They love to do normal stuff together, like bowling or going to Six Flags theme park, and she's been welcomed into his inner circle with open arms.''

Nick has been demonstrating his love and support for his pop star girlfriend by defending her from criticism from her music peers.

Nicki Minaj took a swipe at Iggy at the recent BET Awards, criticising the 'Fancy' singer for using ghostwriters, but Nick insists Nicki is just worried about Iggy's talent.

The sportsman said: ''Iggy is doing big things and that is what is scaring people. She is going to brush it off. She won't let it get to her. She is number one - what can you do? She's at the top right now, so of course they are going to come at you.''
