The feud between Nicole Franzel and Janelle Pierzina is happening inside the Big Brother 22: All-Stars house, but BB13 alumni Rachel Reilly and Brendon Villegas are showing support for their friend. This season marks Janelle's fourth time competing on the show, making her one of only two returning players to have competed on both All-Stars seasons. While their paths have never crossed on Big Brother, Janelle competed against BB12 contestant and BB13 winner Rachel Reilly on The Amazing Race 31. That same season also featured BB16 contestant and BB18 winner Nicole Franzel.

According to Janelle, her Big Brother: All-Stars feud with Nicole Franzel started prior to this season. Janelle claims that Rachel tried to warn Nicole about another team meaning to u-turn her on The Amazing Race. In turn, Nicole allegedly exposed Rachel to the other teams and got them to target Rachel instead. On BB22, Nicole said that she was aware of that drama between her and Rachel. However, she claims not knowing that the fight had gotten Janelle involved as well. Inside the BB house, Janelle and Nicole have shared their own sides of the story. Now, Rachel and her husband Brendon are also chiming in.

Rachel Reilly and Brendon Villegas started dating on Big Brother 13. Rachel was invited to be on this season of All-Stars, but given that she was already pregnant, producers advised her otherwise. In any case, Rachel and Brendon have taken to social media to defend Janelle from Nicole Franzel's claims. First, Brendon tweeted out that he doesn't like what "jealous girls" are saying about Janelle inside the Big Brother: All-Stars house. He added that the people talking about Janelle are insecure, jealous, and narcissistic. Brendon then claimed that these people "will never have the magnetic personalities" that Janelle and Rachel have. An hour later, Rachel sent a tweet praising Janelle as someone who's "fun & full of life/kind & real." Rachel also remarked that her talks with Janelle usually involve their children and jobs... and that they always help and uplift each other to do better.

While Rachel and Brendon never drop any names, it is heavily implied that they are talking about Nicole Franzel. After all, Nicole and Janelle are at the center of what is arguably the biggest ongoing feud on Big Brother: All-Stars. At this point, they have both declared to each of their allies that they are absolutely going to target one another in the game. With that said, Nicole is part of a dominant alliance inside the house and is arguably in a much better position to target Janelle if she wants to.

Considering that Rachel Reilly, Brendon Villegas, Janelle Pierzina, and Nicole Franzel are very high-profile Big Brother contestants, the interactions involving them are always noteworthy. Depending on how the feud evolves on All-Stars, there is a chance that even more BB alum might chime in.
