Kate Walsh is Backless

Kate Walsh dips it low in a super sexy backless gown by Azzaro at The Art of Elysium’s “Heaven: Celebrating 10 Years” anniversary gala held at Vibiana on Saturday in Los Angeles.

“It’s very classic and beautiful from the front,” said one onlooker from the red carpet. “But when she turned around she had that deep plunging back. Breathtaking!”

Kate, 40, was accompanied on the red carpet by movie exec husband Alex Young. What a lucky, lucky guy!
