Charli XCX's definition of success has changed.

The 32-year-old pop star's latest album, 'Brat', has been well-received by fans and critics - but Charli doesn't judge her success by album sales.

She told i-D magazine: "My perspective on what qualifies as success has changed.

"For me, success is the fact that I made this record exactly the way that I have made it: with the people that I love, and I’ve made no sacrifices on it.

"Of course, it’s an added bonus that a lot of people seem to be into it, but that also comes with public takedowns and a lot of other s*** that I don’t necessarily love."

Charli feels she's actually developed a better, healthier perspective on her own career in recent years.

The '360' hitmaker shared: "I was not in any way expecting what happened to happen.

"I knew I’d made a great record. You always hope 'maybe more people will hear this one' but it’s not really what I live or die by.

"I was definitely more prepared because I understood every single thing that I did for this record and why I did it, down to the placement of the font, down to the reason I sing things in certain timbres, down to the way I look. And I also experienced commercial success in 2014 when I definitely was not ready.

"When I think about myself singing 'Boom Clap' or 'Fancy' or 'I Love it' and not knowing why I was doing certain things in certain ways or why I was wearing certain things or why I was even doing things, period … I think from that to now I’m in such a drastically different place with myself and my artistry and with my confidence, to be honest."
