Jennie Garth Shares How Her Clothing Line Honors Late Co-Star Luke Perry (Exclusive)

Perry's death isn't the only tragedy to rock the cast of 90210. Earlier this month, Shannen Doherty died after a cancer battle. The actress, who played Brenda Walsh on the series, was 53.

"We are always there for each other in our moments of need, no matter what they may be. We have a group text and we just call each other," Garth said of how the 90210 cast has supported each other in the wake of the news. "I got off the phone with Ian [Ziering] last night. We're brothers and sisters, so we are very close. It's a bond that is kind of unexplainable and it can never be broken. We're associated with one another for the rest of our lives and we all love it."

As for what Garth wants people to know about her friendship with her late pal, the actress said, "I want people to know that I loved her and we were sisters. We met very young and we did a lot of growing up together and apart. She was just a really neat lady."

Garth previously honored Doherty on her podcast, I Choose Me. It's a medium that the actress has used as a way to have that and other "really intimate conversations with the world."

"I'm really using this platform and this podcast as a way to connect and sort of show our similarities and our connective tissue, no matter who we are or what we do, we're all going through the same things in life," she said. "I like sharing that part with people."

Me By Jennie Garth will have its first release on July 29, followed by drops every month for the next two years on QVC.com.
