So, you're curious about Selena Gomez's age when she was dating Justin Bieber, huh? Let's grab a coffee and dive into that time machine, shall we?

Bieber Fever Strikes

Picture this: it's 2010, and the world is in the grip of Bieber Fever. Justin, with his swoopy hair and baby face, is taking the pop scene by storm. Meanwhile, Selena, our girl from Wizards of Waverly Place, is rising to fame with her own music and acting chops.

Now, you might be thinking, "When did these two start their on-again, off-again saga?" Well, grab your popcorn, because here we go.

First Encounter

It's 2009, and Selena is just 17, still a teenager, mind you. She's at a kids' choice awards show, and who does she meet? None other than the Biebs himself, who's a fresh 15. They're both up for an award, and the cameras catch them chatting. Awkward? Maybe a little. But who knows what sparks fly at that age?

Fast forward to 2010, and they're spotted together again. This time, it's a full-blown date at a movie theater. Selena's 18 now, and Justin's 16. Young love, right?

Official-ish

It's 2011, and the rumors are swirling. Selena's 19, and Justin's 17. They're spotted together all the time, but neither of them is confirming anything. They're doing that thing where they're "just friends" but everyone knows they're more than that. You know the drill.

Finally, in 2012, they make it official. Selena's 20, and Justin's 18. They're young, they're in love, and they're not afraid to show it. Cue the awws and the eyerolls, depending on who you ask.

Growing Up

Now, here's where things get a little more complicated. They break up, they get back together, they break up again. It's a rollercoaster, and they're both growing up in the public eye. Selena's 21, 22, 23... she's navigating her twenties, and Justin's right there with her, turning 19, 20, 21.

Through it all, they're learning, they're changing, they're figuring out who they are as individuals and as a couple. It's messy, it's real, and it's a big part of their lives.

Moving On

By 2018, they've called it quits for good. Selena's 26, and Justin's 24. They've grown, they've changed, and they're ready to move on. It's bittersweet, but it's also a testament to how much they've both evolved.

So there you have it, the timeline of Selena and Justin's relationship in a nutshell. It's a whirlwind, isn't it? But hey, that's life in the spotlight. Now, who's ready for a refill?
