More than a week after his much-debated performance at the American Music Awards, Adam Lambert says he continues to find himself an unwanted guest on ABC.

Late Wednesday night Mr. Lambert, the singer and “American Idol” runner-up, wrote on his Twitter account that his invitation to two more ABC programs had been withdrawn.

“Yes, sadly friends,” Mr. Lambert wrote, “ABC has canceled my appearances” on “Jimmy Kimmel Live” and the annual “Dick Clark’s New Year’s Rockin’ Eve” special.

Last week ABC scratched a planned appearance by Mr. Lambert on “Good Morning America,” its morning talk show. That decision stemmed from Mr. Lambert’s performance on Nov. 22 at the American Music Awards, also broadcast on ABC, during which he simulated sex acts with his dancers, kissed a male bandmate and extended his middle finger to the camera.

In announcing its cancellation of Mr. Lambert’s booking on “Good Morning America,” ABC said it was concerned that he would give another “controversial” performance “so early in the morning.”

On Monday Anne Sweeney, the co-chairwoman of Disney Media Networks and president of the Disney/ABC Television Group, said that ABC was re-evaluating its approach to live shows in the wake of Mr. Lambert’s act and would seek to ensure that artists’ performances more closely resemble their rehearsals. “We certainly don’t want to suppress artistry at any level, but we also have to be very cognizant of who our audience is,” Ms. Sweeney said in an interview with Reuters.

A spokesman for ABC’s entertainment division, which oversees “Jimmy Kimmel Live” and “Dick Clark’s New Year’s Rockin’ Eve,” was not immediately available on Thursday morning.  But on his Twitter account, Mr. Lambert struck a conciliatory tone. “It’ll all blow over,” he wrote. “Let’s focus on being positive!” He also said that he was still booked to appear on “The Jay Leno Show” on NBC.
