The 23-year-old is known for her raunchy stage outfits and wild hairstyles, but now she's sporting a more natural look to try and avoid becoming a 'gimmick'.
Speaking to Ryan Seacrest on his KIIS FM radio show, the We Found Love singer said: 'I kind of just wanted to scale right back instead of having a look. I didn't want to make it such a big deal about what hair colour or what cut [I have]. I just wanted to go right back to something simple and something flexible, something a little more natural. It's more about the music. I don't want to become a gimmick - ever. Well, I ran out of [hair] colours, so that's why I decided to go back to my natural colour.'
