Happy 21st Birthday, Demi Lovato!

by at .  Updated at . Comments

Demi Lovato turns 21 years old today - and the singer has plenty of reasons to pop some champagne!

The birthday girl is set to once again judge The X Factor alongside Simon Cowell, while a recent report said she will also guest star on Glee this fall.

Granted, as explained in one of the following videos, there's an unexpected Demi Lovato nude scandal possibly in the works... but the star has built up so much good will since leaving rehab two years ago that we doubt it will slow her career momentum.

So go right ahead and send Demi your very best birthday wishes today.

And while you're at it, take time to also acknowledge the following famous people who turn a year older on August 20:

  • Andrew Garfield (30)
  • Amy Adams (39)
  • Al Roker (59)
  • Ron Paul (78)
