The Michigan resident has reportedly filed a lawsuit against the popstar, claiming to be the father of Bieber's girlfriend Selena Gomez, reports TMZ.
In court papers obtained by the website, the man makes over-the-top allegations about Bieber and his mentor Usher.
The claims include how Usher sexually assaulted him, and how Bieber stole his credit card to pay for penis enlargement pills, while also cheating on his 'daughter' with Ke$ha, Rihanna and Penelope Cruz.
The currently unnamed man stated in the suit: "Bieber has cost me $426.78 and never paid me back. This money was used as abortion money because Justin Bieber got my daughter Selena pregnant in my bedroom, on my canadian bear rug (sic)."
He continued: "Usher Raymond came to my house on the forth of july 2012 and sodomized me with a firework and lit it inside my anal area while blaring kate perry firework song in my ear drums.
"[Bieber] gave selena a std and Bieber stole my credit card to buy him and sean p-ditty cmobs cocaine to use in drug free school zones. Bieber also got a penis enlargement with my stolen american express card."
The lawsuit ends with the statement: "I'm an emotional mess ... America must boycott biebers music!"
