'Made In The USA' beauty Demi Lovato has opened up about her ever-changing hair colour and revealed that she doesn't care what other people think of her appearance as long as she's happy.

During an interview with People magazine, the songstress confessed that she's currently enjoying her blonde locks and doesn't have plans to dye her mane a different shade any time soon:

"I just kept getting blonder and blonder...The overall reaction is… people like it! I don’t really care if people like it or not. I like being blonde and it’s fun for the summertime.”

When asked about the colour she's likely to try next, Lovato added: "You never know what I’m going to do next. Maybe like a honey brown or a dirty blonde or something, so it’s not too blonde.”

Meanwhile, the superstar recently told MTV News that the new 'X Factor USA' panel is a lot of fun because there's a lot of "girl power" within the group:

"That's fun having a bunch of women on that panel, because it's like girl power and it brings a lighter energy to the show. Instead of having feuds on the panel, there's actually...It's all positive. Therefore it makes it fun to watch."
