Katy Perry has said it would be a “dream” to win an Oscar for Wide Awake from concert movie Part of Me 3D.

The 28-year-old singer could be in contention for an Academy Award nomination in the Original Song category.

Speaking to USA Today, Perry explained that she would be on cloud nine if she were to win, saying: ''It's like a dream's dream. When I was growing up and working on music, it was always a dream to win a Grammy, but Oscar was so far out of my dream sphere.

''This would be a nomination of a completely different calibre. One that is more impressive than many other ones I've had. It's interesting to step out of your playing field and to be recognised from a different angle. It would be an honour.''

Adele is also rumoured to be up for an Oscar for her song Skyfall from the recent James Bond movie of the same name.

The 2013 Oscar nominations will be revealed on January 10 and the ceremony takes place on February 24.
