Bernadette Peters

Currently on Broadway knocking them dead in "A Little Night Music", Bernadette has always been a favorite of mine. She replaced Catherine Zeta-Jones in the role and the New York Times couldn't be gushing more. They call her performance of the song "Send in the Clowns" as, "an occasion of transporting artistry” and “an indelible moment in the history of musical theater.”
Here's the whole review.

A few days later, the New York Times ran a nice follow-up feature on Ms. Peters. My favorite part:

"Ms. Peters is 62... But to say that Ms. Peters doesn’t look her age doesn’t begin to describe her seemingly eternal, Betty Boop-like girlishness. Her porcelain skin is untroubled by wrinkles. Her kewpie-doll smile defies gravity. When she turned up for lunch at an upper West Side restaurant recently, her eye-snagging bosom pillowed distractingly from a low-cut dress, and the humidity had injected an extra jolt of abandon into her trademark corkscrew curls."

Eye-snagging bosom... atta girl! You can read the article here.
