"The 'In Memoriam' segments are always the most moving parts of a major awards show. Robin and I thought it would be fitting to pay longer-form and more personal tribute to these American icons with great stories from their friends, colleagues and peers," Kimmel said in a statement.
Roberts will also anchor a second special Dec. 19 called "The Year: 2017," which will focus on the year's "politics, top trends, pop culture and more."
"What I appreciate about the special is that you get an entire year of news and pop culture in just two hours. The show is appropriately serious when it needs to be, and it's also filled with many fun, lighter moments," Roberts added.
