Beverley Mitchell gave a very clear warning if Justin Timberlake ever hurt Jessica Biel.

Beverley Mitchellwho you may remember best as Lucy Camden on 7th Heavenpopped by to chat with Danielle Fishel, Rider Strongand Will Friedle on their Pod Meets World podcast. It was a celebration of all things retro and ’90s with this crew, especially when Mitchell started talking about her costar and pal Jessica Biel.

Biel, as we’re sure you know, played Mitchell’s older sister Mary Camden on the first six seasons of the series, popping in for guest shots during the remaining five seasons. As it happens, during Mitchell’s madcap youth she became quite close with the gents in the boy band NSYNCwhich included the future Mr. Biel, Justin Timberlake.

She described some of her early adventures, especially ones involving the group’s “Challenge for the Children” charity events, that Fishel was also present for.

“I think one of my most favorite memories was, we were all underage in Las Vegas, running around doing a scavenger hunt. And when I say like scavenger hunt, I mean all over the Vegas Strip. I think I was on Joey (Fatone)‘s team — running through the Vegas Strip with NSYNC like hooligans.”

She continued, “We did it in Miami also, and at that point Cameron Diaz was there. Gabrielle Union. All these superstars running around unleashed, at a time where, like, the cell phone pictures were on a flip phone. We were able to have this kind of freedom to be wild and crazy, but those friendships were just so genuine.”

Both Mitchell and Fishel reminisced about how the bodyguards NSYNC hired were also all incredibly fun, and Mitchell noted that she was still good friends with the fellas from the band, adding, “And it’s very funny that one of them ended up marrying my best friend.”

She continued, “I gave Jessie so much crap because she used to make fun of me. She would be like, ‘You’re hanging out with the NSYNC boys,’ and I’m like, ‘Dude, they’re fun, we have fun.’ And she used to think I was so silly and lame and now you’re married to one.”

Reflecting on how two people close to her hooked up (and have stayed married for nearly 13 years), she said that “when they first started dating (Timberlake’s mother) Miss Lynn was like, ‘Okay, Bev, tell me about her. And I was like, ‘If he hurts her, I’ll kill him.’

About her old 7th Heaven costar, Mitchell said, “She is my sister.”
