Demi Lovato is only 20 years old, but she's already had a really amazing career.

How cute are these old pics of Demi? They show some of her very first jobs as an actress and model.

Demi started working at just seven years old, and she's kept really busy ever since.

The pic on the left is one of Demi's first modeling jobs, which is actually for a children's Sunday school workbook.

The pic on the right is obviously from her days on Barney. Do you know who else was on that show? Selena Gomez! Check out a clip below of the two of them in their very early days.

Demi has definitely come a long way since these two jobs.
