As Miley Cyrus , 19, and Liam Hemsworth, 22, announce their engagement, we can't help but wonder: are they too young to tie the knot? Check out these other stars who married at a young age, and see where it got them.

Miley Cyrus and Liam Hemsworth are getting married, the young couple have revealed.

Miley may be only 19 but she's been in the entertainment industry for half of her life so she's no doubt more mature than a lot of people in their late-20s!

However, is she too young for marriage? The average age for first marriages in the developed world is generally between 26 and 29 (for both men and women) so the former Hannah Montana star is certainly going into it at a younger age than most of her peers.
