She also wears the brand in her racy new video, which has just been released.

Her album has been four years in the making, with Hayden revealing: ' changed so much over the years just because my life experiences and who I am as a person is obviously reflected in the music.'

The result, she says, is collection of 'very different, very diverse' tracks.

Not that Hayden, who dates co-star Milo Ventimiglia, 31, has given up her superhero powers for good.

She's already filming the third season of her hugely popular drama, which she promises packs just as much punch.

'Everyone's so excited about it,' she says.

'It's the same action, the same high-intensity as the first season.'
