UPDATE: E! News has learned that this Twitter account posing to be Sofia Richie is not real. Richie is not on Twitter.
In case you missed it, SelGo called Bieber out for sharing back-to-back photos of Sofia and then threatening to make his Instagram private if people kept hating on her.
Selena wrote, "If you can't handle the hate then stop posting pictures of your girlfriend lol – it should be special between you two only. Don't be mad at your fans. They love you."
Though Justin provided his own response, Sofia also made sure to show her support for him. "Justin is not shutting out his beliebers," she tweeted on Monday. "He's thankful everyday for y'all, y'all got him here.. He doesn't forget that.. Period."
#purposetour is still on... The music is still coming.. Love who you want... Stop the damn hate... And love each other!!— Sofia Richie (@sofiairichie) August 16, 2016
She added, "All love," which seems to be a recurring message throughout all of the drama between SelGo and the Biebs.
Then, after Justin deleted his Instagram account on Tuesday, Sofia tweeted again with a similar message. "#purposetour is still on," she wrote. "The music is still coming.. Love who you want... Stop the damn hate... And love each other!!"
Sofia has already followed her own advice and made sure she (literally) turned off any hate that could be aimed her way, blocking users from being able to comment on her Instagram photos.
Meanwhile, SelGo's commentary eventually led to some big back-and-forth with Bieber that the Internet couldn't help but dissect.
He responded to her first comment, saying, "It's funny to see people that used me for attention and still try to point the finger this way. Sad. All love," he reportedly clapped back in the comments. "I'm not one for anyone receiving hate. Hope u all can be kind to my friends and each other. And yes I love my beliebers."
The "Hands to Myself" singer was not about to let Justin's allegation slide, issuing another not-so-subtle jab toward the crooner on Instagram. "Funny how the ones that cheated multiple times, are pointing the finger at the ones that were forgiving and supportive," she added. "No wonder fans are mad. Sad. All love."
The digital sparring continued as Bieber responded again with some even bigger allegations. "I cheated...Oh and I forgot about you and Zayn [Malik]?" he reportedly commented, according to screen grabs that have since gone viral.
Gomez did not respond right away, and eventually backtracked on her statements. "What I said was selfish and pointless," she wrote on Snapchat late Monday night.
Bieber took things a step further and decided to delete his Instagram account all together.
