Iggy Azalea has called on people to stop ''automatically assuming'' all relationships are ''traditional and monogamous''.

The 27-year-old rapper has taken to Twitter to share her thoughts on the idea of a polyamorous relationship - which involves more than two people - as she said people need to ''stop assuming'' that every romance is the same.

In a series of tweets posted on Monday (02.04.18), she said: ''THIS IS QUESTION IS NOT RELATED TO ME. IAM SINGLE.

''I just wanna know, why is it we all automatically assume everyone in a relationship; is in a traditional/monogamous relationship?

''We should stop assuming that.

''I guess im thinking about the subject because we all talk so much more about sexuality, gender etc. and the ability for those things to be more complex and fluid. But relationships seem to still be assumed to be TRADITIONAL and MONOGAMOUS. why?

''Ive only attempted monogamous relationships, but i know tons of people who have their own versions, that works for them. So i think its odd when we hear about someone stepping out on another person in the spotlight etc. we automatically assume ''cheating'' ''shes dumb'' ''leave''

''HOW DO WE KNOW THE WAY ANYONE ELSES RELATIONSHIP IS SET UP?

''We should stop assuming everyones into monogamy.

''We should also respect that shit is private.

''Be happy, do what works for you. (sic)''

The 'Fancy' hitmaker's positive rant comes after she recently revealed she had spent some time in a ''mental retreat'' in order to deal with her anger issues and poor mental health.

She said: ''I've never really sat down and had an honest conversation with professional people. It was good to say something to somebody who could give me the tools and information on how to make my life manageable when I'm feeling those things. So it was really useful - I'm glad that I went.''
