Actress Shannen Doherty is devastated over the loss of her former co-star and friend Luke Perry. She says his "biggest accomplishment" was his children, who were his heart. "I am in shock. Heartbroken. Devastated by the loss of my friend. I have so many memories with Luke that make me smile and that are forever imprinted on my heart and mind," Doherty, 47, told people.com about Perry, who died on Monday at age 52 after suffering a massive stroke days earlier.

Doherty starred alongside Perry in Beverly Hills, 90210 for years - the actress as Brenda Walsh and Perry as Dylan McKay (he appeared from 1990-95 and again in 1998 until 2000). Although the co-stars drifted apart when the show went off air, they reconnected after Doherty went public with her breast cancer diagnosis in 2015.
