Betty White is mourning the loss of The Golden Girls costar Rue McClanahan, who died on Thursday at the age of 76.

"Rue was a close and dear friend," White, 88, said in a statement.

"I treasured our relationship. It hurts more than I even thought it would, if that's even possible."

White played ditzy Rose Nyland opposite McClanahan's saucy Blanche Deveraux on The Golden Girls, which aired from 1985 to 1992. Rounding out the foursome: the late Bea Arthur (who played Dorothy Sbornak) and Estelle Getty (Dorothy's mom Sophia Petrillo). Arthur succumbed to cancer last April, and Getty died in 2008.

McClanahan had been married six times, and is survived by one son, Mark Bish, from her first marriage.
