HOT IN CLEVELAND/HOLLYWOOD

THE REUNION OF BETTY WHITE, VALERIE HARPER, MARY TYLER MOORE, AND GEORGIA ENGEL HAPPENED TODAY.

I arrived at the studio before Valerie, and you could feel the excitement with Jane Leeves, Wendie Malick and Valerie Bertinelli coming out of their dressing rooms asking if she was here yet? "This is all about celebrating this week," said Jane. "There'll be no sadness on this set. It's all about fun."

When Valerie arrived she was engulfed by cast and crew. People were just beaming, and so was she. Her husband, Tony Cacciotti and I stood by smiling.

Jane, Val, Betty, Wendie, Valerie

This is history. It may be a little blurry, but you see Jesse, Wendie, Betty, Mary, Val and Georgia

"Hot in Cleveland" shoots at the same studio where "Mary Tyler Moore" and "Rhoda" shot. Valerie walked over to me and said, "My darling girl. You were here with me for the very first episode of 'Mary,' and you're here now.'" We fought back the tears.

You could feel the growing excitement as we headed for the table read room. Betty joined us and she and Valerie and Georgia walked arm in arm to the room. Once we entered, Mary stood up to greet everyone. You could see all eyes on this extraordinary reunion. There was applause. There were cheers. Guest stars Jesse Tyler Ferguson and George Hamilton made it even more surreal. When I saw them all seated in a row, I didn't know what planet I was on. Cloris Leachman is also on the show.

Katie Couric is flying out to interview Val for "Katie," "Good Morning America," and "Nightline." Later this week there is a press conference with all the ladies for just about every TV outlet known to man. I have covered events in Hollywood for decades now, and this was emotionally one of the greatest highlights I've ever been privileged to witness.
