Bristol will reportedly be replacing Farrah Abraham, who was axed from the show last season.

The realty star and adult performer was quick to chime in with her opinion about the casting in a statement to Page Six, where she told the outlet: 'MTV has already tried to replace myself with another teen mom' - referring to Teen Mom 3 alum Mackenzie McKee, who was rumored to be joining the cast after Farrah's firing.

'It was unsuccessful and now with another teen mom, they can keep trying to replace but there is not a replacement for me [sic].'

She continued with some strong words for Teen Mom executive producer Morgan Freeman, saying she hoped for 'Bristol and her children safety as [‘Teen Mom’ executive producer] Morgan Freeman is a evil person.'

While Farrah says she was canned for her career in adult entertainment, MTV and parent company Viacom insisted she was fired for being 'too difficult.' 

Palin first pregnancy caused a stir during 2008, when her mom was running for Vice President along with candidate John McCain. 

She was briefly engaged to Tripp's father Levi Johnson, but the couple parted ways by 2009.

Though she's called abstinence the 'only 100& foolproof way' to prevent pregnancies, Bristol doesn't see herself as a hardliner telling Dr. Drew Pinsky she doesn't want to be seen as 'an abstinence preacher' in 2011.

'I'm not out there saying don't have sex. I hate that kind of stuff. Birth control needs to be used effectively each and every single time if you're gonna be having sex. ... I'm not advocating [abstinence] for everyone else,' she told the sex educator and therapist.

Teen Mom OG comes back to screens in fall.
