Renee Graziano Spills on Brandi Glanville, Amber Portwood and More 'Marriage Boot Camp' Drama
Reality Stars -- Then and Now

"Brandi did some things I don't approve of," the "Mob Wives" star tells TooFab.

"Mob Wives" star Renee Graziano is spilling all the tea on her "Marriage Boot Camp: Reality Stars Family Edition" co-stars, just in the nick of time.

During the first episode of the we TV reality series -- which airs Friday night -- "Teen Mom OG" star Amber Portwood has at least three meltdowns, and according to Renee, the first one happened just "two hours into the house!"

"Meeting her, I was nice and warm, but I didn't care for her boyfriend," Renee told TooFab of Amber's now-former fiancé, Matt Baier. "He said he was a very big fan, and I don't consider myself a celebrity. I'm a regular person. Everybody's really regular to me, so I was a little uncomfortable with that. But yeah, Amber's like, not even a firecracker, she's like an M-80 or something because at any moment, it happens."

Graziano said that even though she had to break up squabbles between the "Teen Mom" star and both Brandi Glanville and Jim Jones' girlfriend Chrissy Lampkin, Amber wisely never came for Renee or her sisters, Jennifer and Lana, who are also on the show.

Amber is now dating Andrew Glennon, who actually worked on "Marriage Bootcamp" while she and Matt were filming. Renee told TooFab she had no idea anything of that sort was even going on.

"If I would have know we were able to do that--" she said jokingly. "Honestly, that was a shocker. I can't even find a damn date; this one's finding them on sets!"

Though she and Glanville seem to get alone just fine now, Renee also admitted Brandi did something in the house that rubbed her the wrong way.

"Brandi did some things I don't approve of, sitting on someone's lap when the fiancee's there," she said. "I'm old school. They're lucky I was sleeping when that happened!"

So what's one thing fans will be surprised to see from Renee this season?

"I think my fans are going to be a little surprised at how mean I was towards my sister, and I've apologized to her on every show that I do because I was mean," she said. "I think it was because of years of anger, and a lot of it had to do with my ex-husband, so that anger was there."

"The #1 goal more so for me and Lana to finally air out the resentment, put it down and walk away from it," she added. "I think we had a good experience in it and I'm very grateful for WE tv. Listen, it was not easy, but we were able to come to a resolution and just be like, I love my sisters to death. Nobody’s gonna mess with my sisters and as a unit, the Graziano girls work well together."

"Marriage Boot Camp: Reality Stars Family Edition" premieres Friday at 9 p.m. ET/PT on WE tv.
