With the news that One Direction's Zayn Malik is now engaged to girlfriend Perrie Edwards, we couldn't help but notice that, at 20, they're both a bit on the young side.
Not that there's anything wrong with that.
But it did get us thinking about some other stars who made the same decision.
Here are a few more celebs that didn't let a thing like age get in the way. After all, when you're in love, you're in love, right?
Jessica Simpson: At the age of 21, the singer said "yes" to Nick Lachey's proposal in Feb. 2002. The two went on to tie the knot eight months later, only to get divorced after three years of marriage.
Miley Cyrus and Liam Hemsworth: When she was 19 and he was 22, the couple became engaged in June 2012. Despite persistent rumors of trouble in paradise, the two are still going strong.
Britney Spears: After just three months of dating, the then-22-year-old pop star and Kevin Federline announced their engagement in July 2004 and married in September of that year. The couple had two children together before calling it quits. Their divorce was finalized in July 2007.
Angelina Jolie and Jonny Lee Miller: The Oscar winner and the Elementary star were only 20 and 23 respectively when they made plans to walk down the aisle. While they succeeded in doing so in March 1996, the pretty pair ended the union in Feb. 1999.
Olivia Wilde: Back when she was a wee lass of 19, the stunning star became engaged to Italian prince Tao Ruspoli. The couple exchanged vows in June 2003, but their eight-year marriage ended in 2011.
Macaulay Culkin and Rachel Miner: But Wilde's got nothing on the Home Alone star, who was only 17 when he popped the question to Miner, who was also 17 at the time. They married soon after in 1998, but wound up getting divorced in 2002.
