Leah Messer and MTV don't always get along.

Ahead of the upcoming premiere of Teen Mom 2 season 7B, the reality star and mother of three has admitted in an Instagram post that her relationship with the network has been "horrible" at times.

"This makes me feel the besttttt! You were awesome love. Never let anything hold you back! #DreamBig," Messer wrote in the caption of a photo of herself and a fan.

"At the end of the day.. THIS is what makes 'TEEN MOM 2' worth doing," she continued. "My relationship with MTV may be horrible at times, but making others feel like this girl felt makes it well worth it all at the end! I will set the example these girls need, and we will make a difference!"

Earlier this year, Messer accused MTV of being a "fake" television show after she was seen attempting to get back together with her second husband, Jeremy Calvert.

“Leah wrote that because the show cut out everything on Jeremy’s side,” a source told People Magazine. “He was the one who was begging her to come back and to give him another chance. He was the one that coordinated the date and to try to make it work.”

“The show was edited to make it seem like she was the one doing it and didn’t show anything about Jeremy, and she wanted to set the record straight,” added the source.
