Selena has been all about rekindling relationships from her past this past week. Remember when watched Demi Lovato's Simply Complicated and commented cute supportive comment on Demi's Instagram post? How about when they reunited IRL at the InStyle Awards?\nvia @complex\nWell Selena didn't just stop at Demi. Oh no, she had a super heartfelt reunion with her famous ex-boyfriend, Justin Bieber. Cue the waterworks. Apparently the two have been super close since Selena's kidney transplant. A source revealed to Us Weekly that, “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."\nI’m very aware some of my fans had noticed I was laying low for part of the summer and questioning why I wasn’t promoting my new music, which I was extremely proud of. So I found out I needed to get a kidney transplant due to my Lupus and was recovering. It was what I needed to do for my overall health. I honestly look forward to sharing with you, soon my journey through these past several months as I have always wanted to do with you. Until then I want to publicly thank my family and incredible team of doctors for everything they have done for me prior to and post-surgery. And finally, there aren’t words to describe how I can possibly thank my beautiful friend Francia Raisa. She gave me the ultimate gift and sacrifice by donating her kidney to me. I am incredibly blessed. I love you so much sis. Lupus continues to be very misunderstood but progress is being made.

"Justin and Selena have a lot of mutual friends who brought them back together. They realized it was time to grow past their history and move on. They’re grown up a lot in the past couple of years and are mature about the situation."\nvia @hotlikejelena\nIs it just us or do the words 'back together' make you wanna cry?? The two have had a famously rocky relationship stemming from 2011-2014. Justin has gone on the record saying he'd always love, check-in on and respect Selena. And the feelings are apparently mutual, seeing as Selena had nothing but glowing things to say about her ex's performance for Manchester relief this June, "I thought Justin did great,” she said on SiriusXM’s The Morning Mash Up at the time. “It was really beautiful.”\nvia @miracle7814\nFans of the famous couple were shocked and amazed when TMZ reported JB and Selena were hanging out at her Studio City home a couple days ago until midnight. Though there were a lot of friends also in attendance, it still warms my heart to know the two were hanging out with no complications.\nvia @theweeknd\nAs far as Selena's current boyfriend - remember him? The Weeknd? He apparently has no problems with the two ex-flames getting warm and cozy. “He has been on tour and she’s been travelling back and forth to L.A., but they are 100 percent still on. The Weekend is well aware Selena and Justin are talking," sources claim. Good for these two! Glad to see them being so mature. Maybe one day, when the timing is right, we'll get to see Jelena 2.0.
