Rosie O'Donnell will guest host one week's worth of Jimmy Kimmel Live! episodes from August 17.
The 64-year-old comedian joins a group of stars filling in for the 58-year-old host as he will be "taking the next two months off - this time voluntarily" - referencing when ABC pulled the show off the air for six days in September 2025.
During Kimmel's montage on Thursday's episode of the ABC talk show, he said: "We have assembled a potent group of hosts to fill in for me, beginning with Tiffany Haddish, Colman Domingo, Ike Barinholtz, Anthony Anderson, Jelly Roll."
The comedian then gave a shoutout to O'Donnell, adding: "And, as a special treat for our commander-in-chief, I asked one of his all-time favourites, Rosie O'Donnell, to be here to keep the hits coming."
