It seems Demi Lovato is still in her blue period. The X Factor judge stepped out for the premiere of Disney's Frozen this week with her freshly coloured hair pulled back into a tousled up 'do.

She complemented her azure mane with a neutral makeup palette that featured a shimmering bronze shadow dusted all over her lids. What do you think of Demi's jewel-toned hair?
