Los Angeles: Hilary Duff has been experimenting with her hair colour lately and the singer-actress puts it down to "boredom".
The newly wed star, who recently went back to blonde after going brunette, said that she wanted a change in her appearance, reported People magazine online.
"I was bored and I wanted to dye my hair really really blonde and then I got scared and then it turned out really blonde," she said.
"I haven`t been this blonde and my sister`s like calling me Lizzie [McGuire] which is so funny," said Duff, referring to her star-making role on the Disney Channel.
"I`m like, `No please don`t call me that!` But it might just be that I feel like I`m really blonde because I haven`t been in so long."
But no matter how often she changes the colour and style of her mane, Duff said husband Mike Comrie loves her regardless.
"He loves me blonde, but when we met I had brown hair so I think he loves me anyway."
