Rapper Nicki Minaj has changed her Twitter account name to ‘Mrs. Petty’. The rapper has been dating Kenneth Petty and the name change has left many thinking that she has already gotten married or is in the process. This comes after rumors that Nicki and Kenneth went to the Beverly Hills courthouse early this month and got a marriage license. The rapper kicked off a storm last year when news broke out that she was dating Kenneth, a registered sex offender. Minaj said she was okay with his past. Kenneth was convicted of rape in 1995 and served close to four years for the crime.
