He spoke to Inside Edition as he rehearsed for the "Make America Great Again" show marking the swearing-in of Donald Trump, and addressed the fact that many A-List performers chose to skip it.

“A lot of people say they don’t want to be here," he told Inside Edition. "I'm sorry they're not here." 

Country crooner Tim Rushlow has also been tapped for a major role in the show. On Friday night, he and his band will perform the first dance for the nation's new first couple.

“I am an American and I’d like to think without choosing any side or any party — bringing a little music and hope and joy [will] kick us into being united, would be a good thing. I was honored to be a part of it,” he told Inside Edition.

On Fox and Friends Wednesday, Trump spoke out about the controversy surrounding all those big names who said they wouldn’t be performing at the ceremonies, including Andrea Bocelli, Jennifer Holiday, Paul Anka, Elton John and Garth Brooks.

“I don't want the celebrities there. I want the people there,” he said.

Meanwhile, actress Abigail Breslin is hitting back at trolls who blasted her for hanging out with Trump's daughter, Tiffany.

The Little Miss Sunshine star, who now appears on TV’s Scream Queens, was bombarded by nasty comments after posting a photo of herself at a party with Trump's youngest daughter, Tiffany.

Breslin defending their friendship, saying: “It is honestly disgusting of people to be so cruel to Tiff who is a wonderful and kind person. You need to reevaluate your life.”

TV commenter Marc Lamont Hill is also taking heat for criticizing the African-American celebrities who have met with Donald Trump — including Kanye West, NFL legend Jim Brown and comedian Steve Harvey.

He called them “mediocre Negroes.”

“It's a bunch of mediocre negroes being dragged in front of TV as a photo-op for Donald Trump's exploitive campaign against black people," Hill told CNN Tonight Monday. 

Controversial ESPN anchor Stephen A. Smith says celebrities can play an important role in politics.

He lamented: “Has anyone thought about what impact it could have if Trump spoke to LeBron James? How about Steph Curry? A host of conscientious sports figures connected to communities, committed to helping inner cities from an abyss that has plagued us for centuries?

"What then? Will they be sellouts too? Just for meeting with a man? For expressing their concerns? For articulating what ails these communities? The answer would be no.”
