Iggy Azalea raids Demi Lovato's fridge

Rapper Iggy Azalea has joked that she likes to raid her best friend and singer Demi Lovato's fridge when she runs out of groceries.

"Demi is awesome and it's so cool we live so close to each other because I can just roll down to her house and knock on her door and harass her and eat her food in her kitchen when I don't have any groceries," Azalea told eonline.com.

But Azalea didn't have anyone alongside her as she closed the iHeartRadio Music Awards here at The Forum with her latest song "Team".

The Australian rapper had said she was "nervous" about performing without a fellow artiste, and that she was concentrating on herself after a "turbulent" 2015.

"Everybody knows, it's no secret, I had a bit of a turbulent 2015. I wanted to not breeze over that. I wanted to acknowledge how I felt about it, and I just wanted to say, 'You know what? I think it's fine if everybody doesn't support me because I am a believer in myself.'

"My motto is just like the song says, 'I got me.' Just have your own back. I think we worry a lot about people liking our pages or how many followers we have, and you just gotta worry about your own thing," she said.

Azalea's performance was her first since a video leaked online showing her fiancee Nick Young admitting to his Los Angeles Lakers teammate D'Angelo Russell that he cheated on her.
