"I doubt it will be any kind of an intimate relationship. We always will have some closeness, but I think we have just a marriage of the minds, the two of us, and he's great to work with (William Petersen). A bit of yin and yang in that relationship, for sure." - asked if Catherine's relationship with Gil Grissom might ever turn romantic.

About Madonna: "Life will always be good as long as Madonna is around. I don't think of her as a guilty pleasure anymore - she's an outright pleasure" (In Style magazine, Sept/2006).

We had a murder taking place at a foam party...which once again made me feel so old...So often I'm like, 'What the hell's that?'
