Good Morning America

The people who didn't like Adam Lambert's "American Music Awards" performance won't have to worry about a repeat performance on "Good Morning America" -- cause that gig is canceled.

Leading a guy around on a leash and kissing another was apparently too much for ABC. A rep for the show told TV Newser, "Given his controversial live performance on the AMAs we were concerned about airing a similar concert so early in the morning."

Ironically enough, Lambert announced he was gay on "20/20" earlier this year -- which airs on ABC.

"Good Morning America" co-host Robin Roberts successfully underwent surgery to treat breast cancer yesterday, and the 46-year-old GMA gabber is reportedly already home from the hospital. This past Tuesday, Roberts announced on-air that she was diagnosed with the disease, and revealed that GMA film critic Joel Siegel's battle with cancer prompted her to get checked out.

Her revelation resulted in an outpouring of support -- and an increase in women seeking mammograms and breast exams.

Diane Sawyer skipped out on a party thrown for Chris Cuomo, Sam Champion and other "Good Morning America" staffers last Friday -- and a source says that it's a sure sign that the news diva is planning on leaving the show soon.

Just as the competition heats up with "Today" after Meredith Vieira's arrival, a Sawyer sayonara could be a difficult blow to the ABC morning property. "The staff took Diane's absence as a clear message she is leaving the show," says a source to Rush & Molloy, "and is slowly starting to separate herself from it." Sawyer, say the columnists, had just arrived from interviewing Mel Gibson in his first post-DUI sit-down.

But an ABC rep dismisses any notion of Diane leaving: "She was sick in bed. She called [ABC News chief] David Westin and ['GMA' producer] Jim Murphy to see if she should still come. They urged her stay home."

TMZ has learned New York TV personality Sam Champion will become the new "Weather Anchor" for ABC's "Good Morning America."

Sources say the deal will be inked today. Champion, who did the weather for WABC in New York for 19 years, will leave the station for the network gig beginning the first week in September. We're told Champion will do double duty for WABC on the 5 and 6 p.m. newscasts until the station finds a replacement.

Champion, the perennially boyish blond TV fixture, has been a fill-in weatherman countless times on GMA. He's also substituted for Regis and Larry King on their respective shows.

We're told GMA will make weather a significantly more important part of the show -- hence, Champion's new title, "Weather Anchor."
