CONTENT WARNING: This article discusses sexual assault

Justin Bieber has denied he sexually assaulted a woman in 2014 after her accusation went viral on Twitter.

The woman, who identified herself only as Danielle, alleges the pop singer sexually assaulted her on March 9, 2014, when she was 21. In her account shared on Twitter on Saturday, Danielle said she posted her story anonymously because she wasn’t ready to come forward and reveal herself. She said the alleged assault happened when Bieber was still in a relationship with singer Selena Gomez.

She said she met Bieber at an event hosted by the singer’s manager, Scooter Braun, in Austin, Texas.

Danielle alleges that after the show “a man then approached me and my friends and asked us if we would like to wait after the show to meet Justin.”

“Justin came to us, we took some pictures and chatted for about 20 minutes,” she said, adding that she could not share the photos for legal reasons. She then claims Justin invited her and her friends to the Four Seasons Hotel.

“Justin had made me agree to not say anything to anyone, or I can get in serious legal trouble,” Danielle said.

She alleges: “He then pulled down my underwear, unbuckled his pants, pulled his underwear down, grabbed the bed covers and threw it over us … I was very uncomfortable, and I felt myself starting to hyperventilate. I told him to get off because I was starting to worry about my friends, but it was too late. He forced himself inside me before I got the last few words out.”

Bieber’s representative Allison Kaye refuted the claims, calling it “factually impossible”, in a direct Instagram message to PopCrave. In the DM, Kaye claimed that Bieber was staying at an Airbnb on that date, not the Four Seasons.

On Monday morning, Bieber tweeted, “Rumours are rumours but sexual abuse is something I don’t take lightly.

“I wanted to speak out right away but out of respect to so many victims who deal with these issues daily I wanted to make sure I gathered the facts before I made any statement.”

Bieber also tweeted a link to an article that “shows we didn’t arrive in Austin that night from Selena’s show in Houston until late in the night.”

After Danielle shared her story, another woman – who identified herself as Kadi – alleged Bieber’s bodyguard invited her to the singer’s room after a meet-and-greet in May 2015. She alleged she and Bieber were kissing when things escalated to beyond her consent. She alleged Bieber followed her to the bathroom and locked them inside.

“I asked him to stop and continued to say that I cannot have sex with anyone prior to marriage,” she tweeted. She claims Bieber ignored her and sexually assaulted her.

Kadi has since received backlash after contradicting tweets resurfaced. She defended herself, tweeting, “Most of my mutuals are JB stans and it would’ve been weird if I randomly unstanned him without giving a reason. Because they all know I’ve been a Belieber since 2010. But they don’t know what happened on May 5th 2015. So I just continued to stan.”

At the time of writing, Bieber has not responded publicly to Kadi’s allegation.
