Perrie Edwards thinks up song ideas on the toilet.

The 22-year-old singer has revealed she's always trying to think up a new Little Mix tune and even records song ideas on her phone while going to the loo.

She said: ''I have an idea on my phone from when I was on the toilet the other day.''

However, the star - who is engaged to former One Direction member Zayn Malik - admitted coming up with tracks is not always so easy, even though she claims they wrote over a thousand songs for their upcoming third album.

Speaking about life in the studio, she explained: ''You can be there all day and have nothing and go in the next day and write something in 15 minutes before your car arrives.

''So this album, I think we've written a good 1,000 songs. You can write a little section of a song. A full song or it could be s***e.''

The 'Black Magic' hitmakers went on to say they find their chart success ''really weird'' as it all feels like an illegal substance-driven dream.

Describing their success, she said: ''It's really weird. It's like being on drugs.''

Meanwhile, her bandmate Jesy Nelson revealed while the girl group - also featuring Leigh-Anne Pinnock and Jade Thirlwall - want to be ''together forever'', they dreams of their kids getting together as ''Mini Mix'' in years to come.

She told the Metro newspaper: ''I want us to be together forever. Hopefully, we will have achieved everything we want to achieve because we have big plans.''

Perrie added: ''We'll have a Mini Mix. Imagine if we all had a little girl and they all sang in Mini Mix!''
