Lisa Ann has filed a restraining order against Nikki Benz after claiming that the adult star has been threatening her life. The recently retired porn star says that Nikki and her followers started harassing her last December on Twitter, which continued into January.

Lisa, who appeared in several films with Nikki in the past, says her former co-star also encouraged her followers to attack Lisa online, and things got so bad she couldn't accept her Lifetime Achievement Award at the AVN Awards. 

Nikki responded by saying that she's never threatened Lisa, and claims that the former porn star actually attacked her on Twitter. For now, Benz will have to stay 100 yards away until a hearing next month.
