"I just have to accept that Lauren will never be seen in a bad light," Montag, 21, tells the October issue of CosmoGirl!.
"They don't show the footage of how Lauren was sort of obsessed with [fiancé Spencer Pratt], or how she called my mom in Colorado and told her I was involved in an abusive relationship, or how she would scream at me in the middle of the club if I wanted to leave ... to go see Spencer," adds Montag.
The feud between Montag and Conrad, also 21, is nothing new. It escalated after rumors spread that Conrad had made a sex tape with ex-boyfriend Jason Wahler – rumors pinned on Montag and Pratt.
As for how her own actions are portrayed on the show, Montag tells the magazine that "some of it is true but some of it is a character that they have created" – which is okay with her, because Montag is grateful to be on The Hills at all.
"Every character plays a unique role and makes his or her own contribution," she says. "Even though Lauren and I aren't getting along, I'm still happy to be on this show with her."
