Selena Gomez ''blew'' her first audition.

While the 21-year-old star went on to find fame on Disney's 'Wizards of Waverly Place', she admitted her very first audition as a child was a disaster and executives were not impressed.

She told i-D Magazine: ''I was actually really shy as a child. My first audition did not go well. I was very awkward. It was in front of a bunch of suits at Disney and I definitely felt I blew it. It took me a long time to let go.''

Selena is a huge fan of fellow child star Britney Spears - who first found fame on Disney's 'Mickey Mouse Club'- and still counts one attending of her concerts as ''the best day of my life''.

She explained: ''The 'Baby One More Time'... concert was amazing. I sat all the way up in the nosebleeds and I could barely see her, but I remember it being the best day of my life. I had my hair in a ponytail and I knew all the words to the songs. I'll always remember it.''

Although Selena has been called one of the most beautiful women in the world, she concedes that Photoshop does help her to look good.

She said: ''It's so easy to wear incredible, beautiful dresses and look super glamorous, because you have the power of Photoshop, but a shoot that's really stripped-down and raw is really fun to do.''
