Oprah Winfrey is the latest celebrity to join Jimmy Kimmel's seventh post-Oscar special.
ABC made the announcement Thursday.
Winfrey is making a rare late-night appearance at a time when her year-old cable channel, OWN, is trying to attract viewers after a rocky start. She's been more visible on the channel as well, with a new weekly series, "Oprah's Next Chapter."
Billy Crystal, who is hosting the Oscar ceremony, will help kick off "Jimmy Kimmel Live: After the Academy Awards." Nominees Meryl Streep, George Clooney and Martin Scorsese will be among the stars on hand.
A performance by Coldplay will wrap up the show.
Kimmel's Oscar-night special has yielded comedy pieces that became online sensations, including one with Sarah Silverman and Matt Damon and "Handsome Men's Club" featuring Matthew McConaughey and Sting.
The Oscars will air from a Hollywood theater Feb. 26 at 8:30 p.m. EST, with Kimmel's show to follow the awards and local newscasts.
ABC is owned by The Walt Disney Co.
