She alleged that after the show "a man then approached me and my friends and asked us if we wanted to meet Justin."
She then claimed that she and her friends joined Bieber at the Four Seasons hotel, at which point she consented to them kissing.
However, Danielle alleges that their kissing led to the singer removing her pants, at which point she asked him to stop.
"I told him this was going too far and we should stop because I needed to find my friends," she wrote.
She then said Bieber allegedly told her "they were all OK," before forcing himself on her.
After Danielle posted her account, Twitter user @ItsnotKadi came forward alleging that Bieber had raped her in 2015.
Kadi wrote that Bieber's bodyguard invited her up to the singer's room after a meet-and-greet and they kissed - but that things escalated beyond her consent.
"I asked him to stop and continued to say that I cannot have sex with anyone prior to marriage," she claimed. However, she claims that he ignored her protests and sexually assaulted her.
While Bieber's representative Allison Kaye has refuted Danielle's claims, Kaye is yet to comment on Kadi's allegations.
