Rosie O'Donnell guest-hosts ABC's 'Jimmy Kimmel Live' the week of Aug. 17, 2026, filling Kimmel's summer-rotation slot. O'Donnell told Variety the offer "came out of the blue": the two had never spoken in person and she described their relationship as adversarial. She accepted only after confirming Kimmel himself had made the approach.
