After canceling [article id="1626998"]Adam Lambert's scheduled appearance on "Good Morning America"[/article] last week, on Thursday it was reported that [article id="1627490"]ABC has decided not to book Adam Lambert[/article] for two more specials on the network, following his provocative performance at the American Music Awards last month.

Lambert confirmed via Twitter on Wednesday that he has been unbooked from a December 17 performance on "Jimmy Kimmel Live," as well as the annual "Dick Clark's New Year's Rockin' Eve With Ryan Seacrest."

And after calling ABC's decision to cancel Lambert's "GMA" appearance "disappointing," [article id="1627089"]gay-rights organization GLAAD[/article] has issued a statement addressing the subsequent cancellations:

"Since his American Music Awards performance occurred, GLAAD has consistently advocated that Adam Lambert and openly gay artists not be held to a double standard. As we have expressed publicly, it is disappointing that ABC will not give Lambert a chance to perform at this time. GLAAD's discussions with ABC focused on confirming that his sexual orientation was not a factor in their decisions. ABC confirmed this is not about a same-sex kiss or his sexual orientation but about being 'caught off guard.' "

GLAAD went on to say that the network hadn't clarified to them what "caught off guard" meant after they followed up with the network.

Meanwhile, "American Idol" judge Kara DioGuardi told E! Online that she understood why ABC decided not to move forward with those Lambert appearances.

"We're living in a pretty bad economic time, so they have to do what they have to do to keep their advertisers," she said. "Networks are doing what they think their viewers want and don't want, so it's just budgetary. ... We always know he's going to shock us, right? He's going to wow us and give us the unexpected, and that's his thing. ... That's what we look for."
