“American Horror Story” duo Emma Roberts and Evan Peters made headlines on Monday for their surprise engagement after two years of dating. While the actors' decision to tie the knot may have caused surprise due to the engagement coming just six months shy of their alleged domestic dispute scandal, the pair is also garnering attention for their decision to wed at the age of 26 (Peters) and 22 (Roberts). In honor of the couple's pending nuptials, here are eight other celebrity couples who also got engaged and/or married at a young age:
