Charli XCX feels ''more confident'' in herself following the response to her two mixtapes, 'Number 1 Angel' and 'Pop 2'.

The 26-year-old singer released the two tapes in March and December of last year respectively, and has said her fans' positive reactions to the tracks - which feature a number of guest vocalists including Carly Rae Jepsen, Tove Lo, and Raye - have helped her to understand her ''power as a curator and a collaborator''.

When asked about the response to the mixtapes, the 'Boys' hitmaker said: ''I feel really, really happy and good about it, and I think since I released those two mixtapes, I feel like a lot of things have changed around me, and for me. I definitely feel more confident in myself as an artist. I think those two mixtapes have really helped me understand my power as a curator and a collaborator, and they helped me realise that that's my favourite thing to do. It's less about being front and centre and more about being surrounded by really fun, collaborative people and doing something together.''

Despite having released two mixtapes and several singles since her last full album, 'Sucker' - which was released in 2014 - Charli says she doesn't have a plan when it comes to her music in the future.

Asked if she's planning a third studio album, she said: ''You know, I don't really know. I don't really have a plan, so to speak. I'm just kind of releasing what I want when I want. I'm not sure what's next. Maybe it's an album, maybe it's not an album, maybe there's never an album, maybe there are 10 more mixtapes. I'm just kind of doing what I want to do and seeing where I go.''

The '1999' singer has spent most of 2018 on the road with Taylor Swift and Camila Cabello for Taylor's 'Reputation World Tour', and says the experience has been ''really positive''.

Speaking to Entertainment Weekly magazine about the tour, she said: ''It's been really great. It's kind of a bummer that it's coming to an end. I think it's really cool that she is so open with Camila and me - we perform with her each night. The vibe is really positive, it feels very relaxed. It just feels like we've all got each other's backs, and that feels really nice. It's a good vibe and it's been a really good experience.''
