Even if she is already 21 years old, Selena Gomez still cannot help but yearn for her Disney days. Gomez first became known for her role in Disney's 'Wizards of Waverly Place' as  the smart wizard Alex Russo.

''I miss it. I wish I was still a part of it. I think it was the perfect thing for me at the time I was 14,'' gushes the 'Come and Get It' songstress. Gomez also emphasizes that she still cannot feel that she is now a grown-up artist.

Acting in 'Spring Breakers', releasing various albums, altering her fashion style, and dating Justin Bieber are things that make her far from a child star but for the 'Monte Carlo' actress, she still feels 15 at times.

In an interview with Marvin Humes for UK TV show, the brunette beauty talks about age: ''There is not really a formula. I don't really know if I have fully made the transition yet. I feel like half the time I feel like I'm 15 and then I feel like I'm 21 then I feel like I'm 30 when I'm sitting at home by myself on a Friday night watching the same episode of 'Friends."
