​In Photos: Justin Bieber and Selena Gomez’s rollercoaster romance

It was early 2011 when teenage superstars Justin Bieber and Selena Gomez finally confirmed that they were a couple.

But their love story hasn’t always been a collection of sweet Instagram opportunities and kisses at sporting events. The pair have had their share of ups and downs, as well as more than a few makeups and breakups.

They first split in January 2013, with the “Boyfriend” singer stating, “I don’t know what’s going on in my life.” They reunited three months later, with Justin uploading a photo to Instagram along with the caption, “You’ve been makin [sic] music too long babe come cuddle.”

In early 2014, however, their relationship seemed officially over. Selena checked into rehab for two weeks and posted Instagram snaps with captions like, “taking my power back.” Meanwhile, reports flourished that the Spring Breakers actress was linked to One Direction singer Niall Horan.

But fans who have lamented the young couple's splotchy dating record can be put at ease, because Selena and Justin seem to have reunited once more. Most recently, they took a romantic getaway to Canada, where they enjoyed a relaxing horseback ride, a trip to a Tim Horton’s and some adorable hand-holding.

This duo has certainly come a long way since 2010, when Selena reportedly proclaimed, “He’s like my little brother!” Here, we look back at the most memorable photos from Justin and Selena's complicated love affair.
