A second woman has accused Riff Raff of sexual misconduct just days after the US rapper's Australian tour was axed in response to allegations of sexual assault and rape.
As Jezebel reports, 20-year-old Kelsey Doucette, alleges the incident with Riff Raff occurred at Vans Warped Tour in 2015 when she was 17.

Doucette alleges that after being invited on to the Houston artist's tour bus, he forcibly "pulled [her] hand" and "made [her] lay down" on a bed where he began to touch her legs and arms, tried to kiss her on the lips and asked to have sex.
“Even though I kept swatting his hands away and stuff and just kind of nonchalantly moving them away from me, he kept trying to touch me and trying to kiss on my neck... and at that point I was like, please stop, don’t do this anymore,” Doucette said.
It's also alleged that at one point Riff Raff whispered in her ear, “I’ll even let you have my babies".
Doucette claims she was able to get off the bus after telling Riff Raff she had to leave.
Riff Raff is yet to respond to any allegation made against him.
It comes after a Melbourne woman accused Riff Raff of drugging and raping her backstage at a concert in 2013.
Melbourne venue Corner Hotel has announced it will host a panel discussing sexual harassment and abuse in place of the now-cancelled Riff Raff show.
