Boy George and comedian Jon Lovitz will join rocker Vince Neil on the new season of America's Celebrity Apprentice.

Arnold Schwarzenegger has replaced Donald Trump as the business contest show's frontman, and he's bringing out the big guns for his debut.

New mum Tyra Banks, Jessica Alba, and financial guru Warren Buffett will join Arnie as advisers to the celebrity contestants keen to show off their business skills.

Muhammad Ali's daughter Laila, actress Brooke Burke-Charvet, singer Carnie Wilson, and reality TV stars Nicole 'Snooki' Polizzi, Kyle Richards and Porsha Williams will also take part in the new season of the hit show.

The casting news comes just hours after former model Banks announced she had become a new mum via a surrogate.

The America's Next Top Model host surprised fans on Wednesday (27Jan16) by revealing she and her boyfriend of two years, photographer Erik Asla, had become parents to little York Banks Asla.

"We are so excited for our new baby boy bundle of joy," Banks said in a statement. "The journey to now has not been an easy process, as I've shared before. But there was a beautiful bright light at the end of the tunnel for me and his father, Erik."

Banks, 42, also shared the news on her page by posting a photo of the tot's tiny hat, along with the caption, "The best present we worked and prayed so hard for is finally here. He's got my fingers and big eyes and his daddy Erik's mouth and chin.

Meanwhile, Donald Trump left the programme last year (15) after announcing his decision to run for U.S. political office. The property tycoon is among the frontrunners in the race to replace President Barack Obama.
