Frank Sinatra had some unkind words about Kitty Kelley, whose new unauthorized biography on Nancy Reagan implies that the famous crooner and the former first lady had an affair in the White House.

Early in his concert Thursday night at the Desert Sky Pavilion, Sinatra said: "I hope the next time she is crossing a street, four blind guys come along driving cars."You should not degrade the president's wife in Washington. She is a great lady."

Sinatra concluded his salvo by saying if Kelly were a man, "someone would be whacking her out every 15 minutes."

Kelley's book on Reagan is a hot seller. She also wrote an unauthorized biography of Sinatra, published in 1986.
