Bachelorette alum Wells Adams and his girlfriend, actress Sarah Hyland, will also reportedly appear in an undisclosed role.
The Wrap confirmed Lil Jon, Bass and Burgess will serve as guest hosts.
Page Six said the guest hosts will "rotate" during the season.
News broke Tuesday that longtime Bachelor host Chris Harrison will permanently exit the franchise after nearly 20 years. Harrison had been on a leave of absence since February, when he apologized for "speaking in a way that perpetuates racism" in an interview with former Bachelorette Rachel Lindsay.
Harrison said in an interview with Good Morning America in March that he planned to return to the Bachelor franchise.
"I am an imperfect man, I made a mistake and I own that," he said. "I believe that mistake doesn't reflect who I am or what I stand for. I am committed to progress, not just for myself, also for the franchise."
Harrison will reportedly receive an eight-figure payout.
Katie Thurston's season of The Bachelorette is underway with former Bachelorettes Tayshia Adams and Kaitlyn Bristowe as co-hosts.
