Instead of focusing on the break up, let's take a look back at some of Justin and Selena's sweetest moments caught on camera!
Long before they were even dating, Justin serenaded Selena with his song One Less Lonely Girl at Dick Clark's Rockin New Year's Eve in 2009.
Rumors of a relationship began at the end of 2010 and were heightened when the duo was photographed looking pretty chummy while hanging out in Miami in December of that year.
Justin and Selena finally made their first public appearance as a couple at the 2011 Vanity Fair Oscar Party in February.
At the Billboard Music Awards in May 2011, Justin and Selena were even seated next to each other and spent the evening side by side.
Next, the couple hit Hawaii for a vacation together in the spring of 2011 -- and they packed on the PDA all week right in front of the cameras!
Selena supported her man (and looked fabulous while doing it) at the 2011 ESPY Awards in July, where he was a presenter.
The young lovebirds had no problem showing their affection for one another in August 2011 at the Teen Choice Awards!
Justin left Selena blushing on the red carpet at the 2011 MTV Video Music Awards after she interviewed him as co-host of the preshow.
The couple took some time off in September of 2011 for a romantic beach date in Malibu, where they indulged in some PDA, as per usual!
For one of many of Justin's grand romantic gestures, he took his lady love on a private helicopter ride in Rio de Janiero, Brazil.
Selena and Justin made headlines again when they walked the red carpet together at the November 2011 American Music Awards and barely left each other's sides the entire night! Awww!
In February 2012, Selena and Justin played house for the day when they took his younger siblings to the beach for some play time.
The couple kept it super casual for a lunch date in California back in April and walked hand-in-hand to their car afterwards.
In one of their greatest PDA moments to date, Justin and Selena smooched for the world to see while on the kiss cam at a Laker's game in April.
Later that month, Selena paid a visit to her man on the set of his music video for Boyfriend... and clearly, she was marking her territory!
The couple hit the Teen Choice Awards together once again in July 2012.
After that, Justin's schedule began to get crazy as he started rehearsals for his Believe tour, which began in September. It was the couples' crazy scheduling that ultimately led to their demise -- but they've made it work before, right?! I'm not ruling this one completely over just yet!!
Do you think Justin and Selena will ever get back together?
