"You know what conversation really didn't sit well with me was the stuff between Tammy and Kelsey," the 28-year-old pilot told former The Bachelor star Nick Viall on Wednesday's episode of The Viall Files podcast.
Tammy expressed on The Bachelor's February 3 episode how Kelsey was allegedly "emotionally unstable" and "popping pills" to cope with the stressful process. She also suggested to Peter that Kelsey had alcoholic tendencies.
Kelsey firmly denied both having a drinking or pill problem and felt Tammy was way out of line for suggesting such things and not minding her own business.
"Seeing that kind of interaction go back and forth -- when I canceled that cocktail party in Costa Rica -- that was B-S, to be honest. I don't stand for that at all," Peter said.
"Tammy calling out Kelsey that way and accusing her of that kind of stuff, I don't stand for."
Nick suggested on the podcast Tammy was "unraveling" at that point and looking to stir up drama over the littlest things, and Peter agreed Tammy was in "attack mode a little bit."
"I definitely remember my interactions with Tammy, I enjoyed them. I definitely admired her, and I still do," Peter acknowledged.
"You know, she's a super hardworking person, has a lot of amazing qualities -- but seeing her, the way she kinda attacked Kelsey, attacked and talked with [Sydney Hightower], that's the stuff I didn't like."
After Kelsey refuted Tammy's 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 therefore 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.

The February 5 episode showed Peter facing 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.
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 send Tammy packing. (However, Peter also eliminated Mykenna at the subsequent Rose Ceremony).
While The Bachelor's February 5 episode was airing, Tammy tried to make light of the situation by tweeting, "So sometimes I'm a little bit of a bitch. WHO hasn't been? #TheBachelor."
But after seemingly receiving a lot of backlash from The Bachelor fans, Tammy issued a real apology via Twitter on February 7 and admitted she tends to "gravitate toward humor" in difficult times.
"Ok I'm going to address this once and for all -- remember that this is a show. I do take responsibility for my actions and I never intended to hurt anyone," the house flipper tweeted.
"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.
