When it comes to costars turned best friends, Beverley Mitchell and Jessica Biel are a fan-favorite duo, but it wasn’t always smooth-sailing between the 7th Heaven alums.

During a Monday, July 7, appearance on the “Catching Up With the Camdens” podcast, Mitchell and Biel’s on-set teacher Cheryl Diamond recalled “refereeing” arguments between the pair behind the scenes of the family drama.

Mitchell, 44, then shared her recollection of her past disagreements with now-best friend Biel, 43.

“I actually distinctly remember a conversation where I was dealing with faith, and I was very hardcore in my Christian faith at that time, and Jessie was challenging me,” Mitchell said. “I remember that you played referee, and you’re like, ‘I am in the middle of this conversation between these two, and there’s no right or wrong.’ And I’m trying to just, like, play nice because it was our first real debate, and I just remember you managing us very well.”

Although Diamond did not recall the exact argument Mitchell was referring to, she noted that she “refereed” conflicts between Mitchell and Biel regarding their “different learning styles.”

Mitchell then chimed in that her clashes with Biel were bound to happen from time to time.

“I also think that because Jessie and I were so close in age that it’s like we were meant to battle. And Jessie also knew, like, it brought her great joy to push my buttons,” Mitchell said with a laugh. “And I didn’t know how to recognize when she was doing it on purpose.”

Biel and Mitchell starred as sisters Mary and Lucy Camden, respectively, on 7th Heaven, which followed a minister and his wife as they raised seven kids. While Mitchell remained a member of the main cast throughout the WB and CW series’ 11-season run from 1996 to 2007, Biel made the shift from a series regular to a recurring cast member in season 7 and returned as a special guest in seasons 8 and 10.
