• January 2017: Selena then began dating The Weeknd [62], and Justin did not seem too pleased with the news. [63] Shortly after photos emerged of the new couple packing on the PDA [64] outside of an LA restaurant, photographers caught up to Justin and asked him if he listened to the fellow Canadian's music. Before the photographer could even finish his question, Justin replied, "Hell no, I can't listen to a Weeknd song! That sh*t is wack."
• June 2017: Even though Selena never addressed Justin's comments, the singer had nothing but nice things [65] to say about her ex following his emotional One Love Manchester performance [66]. "I thought Justin did great," Selena said in an interview with Sirius XM's The Morning Mash Up. "It was really beautiful."
• October 2017: A few months later, it looked like Selena and Justin finally mended fences. After Selena revealed that she had a kidney transplant [67] over the Summer, the exes reportedly began speaking [68] "a couple months after her surgery." Justin was spotted arriving at Selena's home on Oct. 22, and they allegedly hung out with mutual friends until midnight. "Selena is simply trying to make peace with Justin after her illness," a source told Us Weekly. "He has been great to her since her surgery and they are on good terms right now. They got back in touch recently through their friends and have seen each other at church [69]." "They realized it was time to grow past their history and move on," another source added. "They've grown up a lot in the past couple of years and are mature about the situation."

• November 2017: On Nov. 1, the two were spotted getting cozy during a stroll in LA [72]. Later that evening, Selena sported Justin's jersey [73] as she cheered him on at his hockey game. The following day, a source confirmed that the former couple was giving their relationship another go. "Selena and Justin are back together [74]," the insider told Us Weekly. "Selena and The Weeknd just fizzled and ended amicably — it wasn't dramatic and it wasn't about Justin. But Selena always had feelings for Justin. Her friends want her to be cautious because she has been in such a good place post-surgery."
• December 2017: In an interview with Billboard, Selena opened up about her decision to take Justin back [75], saying, "I cherish people who have really impacted my life. So maybe before, it could have been forcing something that wasn't right. But that doesn't mean caring for someone ever goes away. And [that goes for] people in general." Still, that doesn't mean Selena and Justin weren't having problems. Not only did Selena reportedly walked out on Justin [76] during one of their dates in Seattle, but Selena's mom, Mandy Teefey, was not on board with the reconciliation [77], which caused some tension between her and Selena [78].
