BFFs Demi Lovato and Selena Gomez star in the Princess Protection Programme, but they're anything but spoilt in real life!

Demi and Selena recently had their own special edition People scrapbook dedicated to their friendship but they just got even cuter, as they reveal just how sweet and princessy they are.

Demi admitted that her most princessy quality is her love of high heels, that she blames on her childhood Cinderella pageants.

But good girl Selena added that her most princessy quality is 'helping people all the time'. Selena just can't help doing good deeds and is always there for her friends, as Demi will agree.

But is this really Selena's most princess-like behaviour?  Doesn't she ever throw a strop after a long day of filming, or if she gets the wrong kind of milk in her cappuccino?  Well, we'll just have to take her word for it.

Watch Demi and Selena talk princess behaviour...

Do you think Demi and Selena are real life 'princesses'?  How princessy are you?
