Brooke Wehr hasn't yet appeared on Teen Mom 2, but already, she's been a target for fans of Leah Messer.

Several months into her relationship with Jeremy Calvert, Messer's ex-husband, Wehr is preparing for her MTV debut while fighting back against Messer's unruly fans with re-tweets.

While fans will soon meet Wehr on the show, they may not see much of her relationship with Calvert in the coming months as he's reportedly planning to quit Teen Mom 2 after season seven.

“Jeremy is over it,” The Ashley's Reality Roundup’s source revealed last month. “He’s tired of being attached to this show, and now that he and Leah are divorced, he doesn’t want to be part of her drama. He’s tired of dealing with all the negativity that comes from him being on the show, too.”

Calvert also wants his 3-year-old daughter with Messer, Adalynn Faith, off the show -- and there's not much MTV can do about it if he refuses to sign a filming waiver. 

“There’s no way MTV would fight it,” the source explained. “They won’t go to court or anything. It will make it very hard for the film crews, though, if they are filming Leah and the twins and Addie is not allowed to appear. They will probably try to throw a lot more money Jeremy’s way to get him to agree though, but that’s the most they’ll do.”

However, that isn't exected to work with Calvert.

“Jeremy’s one of the only cast members with a ‘real’ job,” the source said. “He makes an impressive amount of money on his own, so money’s not really an issue for him like it is with some of the other cast members who completely rely on their ‘Teen Mom 2’ income to live off of."

For more of Jeremy Calvert and Brooke Wehr, tune into Teen Mom 2 season seven on Mondays at 10 p.m. on MTV, and check out a sneak peek at next week's episode below.
