Jennie Garth finds it "very hard to understand" Luke Perry and Shannen Doherty's deaths.
The 52-year-old actress admitted she still considers her former 'Beverly Hills, 90210' castmates as being "alive in [her] mind" so struggles with the fact she is no longer able to see or speak to them after Luke died in 2019 following a stroke and Shannen passed away from cancer last July.
