"Ok I'm going to address this once and for all -- remember that this is a show," the 24-year-old house flipper tweeted on Friday.
"I do take responsibility for my actions and I never intended to hurt anyone. I am very sorry to those I did hurt but my heart was never coming from a intentional malicious place."
Tammy was accused of trying to eliminate girls in the running for Peter's heart rather than focusing on the advancement of her own relationship with The Bachelor star.
Tammy's approach to dating seemed to be throwing other women under the bus and warning Peter about ladies who allegedly had poor intentions or weren't ready for an engagement.
Tammy expressed how Kelsey was allegedly "emotionally unstable" and "popping pills" to cope during the process. She also suggested to Peter that Kelsey had alcoholic tendencies and seemed to turn to drinking in difficult times.
But after Kelsey refuted such claims during a private chat with Peter and earned herself a rose, Tammy appeared to turn her attention towards Mykenna, who also made a habit of crying over Peter.
Tammy told Peter that Mykenna was overly emotional and immature, adding that the fashion blogger was using the show as a way to create hashtags and brand herself.
Tammy went on to tweet on Friday that she tends to "gravitate toward humor in situations like this" because she is "not trying to mourn in the past mistakes I've made."
"We're all human," Tammy continued. "All of us have done things we're not proud of. So please hear me when I say -- I never meant to hurt anyone and I'm sorry."
"My 5 minute 'nasty' moment on TV doesn't define who I am," she added on Twitter.

"Just like how your mistakes don't define who you are either. Remember that all of us who participated in this show are human too and some of you say nastier things to us than we do to each other."
Tammy then begged her followers to give her a break and cut her some slack.
"Can we PLEASE get back to making playful fun of my ugly faces now #ComedicRelief," Tammy concluded.
In the latest February 5 episode, Peter faced all the drama head-on by asking Tammy and Mykenna on a two-on-one date in Santiago, Chile, so he could get to the bottom of things and hear them both out.
After Mykenna complained to Peter about how Tammy allegedly enjoyed bringing other girls down in order to boost herself up and make herself seem more desirable, Peter chose to believe Mykenna and oust Tammy.
