Justin Bieber has filed a $20million (£16m) defamation lawsuit against the two women who accused him of rape, it's claimed.

Axar.az reports citing foreign media that last week the two women took to Twitter to say that the singer, 26, sexually assaulted and raped them in 2014 and 2015 respectively when he was in a relationship with Selena Gomez.

Shortly after Justin took to the website to post a series of tweets denying the first woman's allegations, saying he was with Selena at the time and not at the location where the accuser said he raped her, but he is yet to comment publicly about the second woman's allegations.

Legal documents were seen by People reportedly show Justin issuing the two women for $10million (£8m) each.

Justin's lawyers allegedly say their allegations are "factually impossible, and disproven both by indisputable documentary evidence and the individuals’ own admissions."
