Britney Spears earned 'cool points' with her kids for Iggy Azalea collaboration

Songstress Britney Spears has revealed that her sons, Sean Preston (9) and Jayden James (8), convinced her to collaborate with rapper Iggy Azalea because they think she's 'cool'.

Speaking to Dan and Maz on 2DayFM, the 'Till The World Ends' sensation admitted that she got some major 'mom points' for her duet with Azalea on 'Pretty Girls':

"She's absolutely a doll. She's so sweet and just a very grounded person, and her accent is absolutely beautiful and my kids love her too. My kids were like, 'Mum, you have to do a song with Iggy, she is so cool!' So I was like, OK, I get points for that."

Little Mix co-wrote 'Pretty Girls' and revealed that the track didn't quite fit their sound so were amazed when Spears wanted it: "Well as we were writing the song we realised that it sounded more like it should be for somebody else rather than us. We absolutely think that it's perfect for Britney. She's absolutely smashing it at the moment."
