Cameron Diaz, Mike Myers and Melanie Griffith are among the stars who have sent their best wishes to veteran U.S. newswoman Barbara Walters as she recovers following heart surgery.

The 80 year old underwent an operation last week to replace a faulty heart valve, and over the weekend a rep for the star confirmed the surgery was a success. Now Cameron Diaz has led tributes to Walters, wishing the broadcaster a speedy recovery. She tells ETOnline.com, “(She is an) extraordinary woman. I send her all the healing white light and love that I’m sure is surrounding her right now.”
