This week, Richie released a collection of his classics performed with top country acts, and is set to appear at Sunday's ACM Awards. The next day, he'll be feted at an all-star concert.
Anthony is scheduled to perform Richie's song “Endless Love” with Sara Evans during the CBS special, which will air April 13.
In a statement released Friday, Anthony said Richie was “one of the soundtracks of my life growing up.” He also called Richie an icon and said he was honored to be a part of the tribute.
