The first thing we thought when we heard the news last week that Zayn Malik from One Direction is engaged was, "OMG, but he's so young!" See other stars who put a ring on it (some that stayed together, some that didn't) before the age of 24, like Reese and Ryan, Miley and Liam, Heidi & Spencer and more.
Zayn Malik and Perrie Edwards Engagement
Directioners found out that Zayn popped the question to Little Mix's Perrie right around the time of 1D's movie premiere in London. Congrats on EVERYTHING, you guys!
Reese Witherspoon and Ryan Phillippe Wedding
Reese Witherspoon has admitted to being "ridiculously young" when she and Ryan got hitched in 1999 when she was just 24. They're divorced now, but they've got two kids together so that's gotta count for something.
Hilary Duff and Mike Comrie Wedding
Mike Comrie proposed to Hilary Duff when she was only 22. Now, she's 26, a mama, and couldn't be happier!
Max George and Michelle Keegan Engagement
Max George from The Wanted was engaged to soap star Michelle Keegan when he was 23, but now they're broken up and he's a major ladies' man. Love it.
Blake Jenner and Melissa Benoist Engagement
Although these Glee guys still have yet to confirm their engagement, it's reported that 21-year-old Blake Jenner popped the question to his slightly over girlfriend in July. At 24, she's totally a cougar.
Britney Spears and Kevin Federline Wedding
Britney Spears and Kevin Federline got engaged and married when Brit was only 22. Three years later and a mom of two young boys, KFed and Brit Brit called it quits.
Alex Pettyfer and Riley Keough Engagement
Alex Pettyfer was rumored to have proposed to his then-girlfriend, Riley Keough, when he was barely 22 years old. They're no longer together.
Heidi Montag and Spencer Pratt Wedding
We can't keep up with the amount of weddings that the former stars of The Hills had. But we do know that Heidi was only 22 when she married Spencer in '09. Youngins.
Shenae Grimes and Josh Beech Wedding
Shenae Grimes and her boo, Josh Beech, got engaged last December when she was only 23. But now, they're married and still going strong!
Avril Lavigne and Deryck Whibley Wedding
Avril Lavigne and Deryck Whibley got hitched when there were just kids—she was 23 at their wedding—but they got divorced just over three years later. 26 and divorced is not such a good look.
Jessica Simpson and Nick Lachey Wedding
Jessica Simpson and Nick Lachey were married for only three years during which Jess was ages 22-25. Now, she's in her early thirties, engaged again and a mama of two, so clearly only good came out of this.
Alexa Vega and Sean Covel Wedding
Alexa Vega will always be a Spy Kid to us, hence why her marriage (and eventual divorce) to filmmaker Sean Covel always felt weird. She was 21 when they got hitched!
Miley Cyrus and Liam Hemsworth Engagement
When he was 22, Liam Hemsworth popped the question to then 19-year-old Miley Cyrus. These two are still together but are not yet in wedding-planning stage, despite the rumors of a breakup.
Jamie Campbell Bower and Bonnie Wright Engagement
Before he was romancing Lily Collins, Jamie Campbell Bower was engaged to his Harry Potter co-star, Bonnie Wright, for a year before calling it off. He was 23 when they broke up.
