LOS ANGELES (AP) — 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.

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 a “Handsome Men’s Club” featuring Matthew McConaughey and Sting.

The Oscars are Feb. 26, with Kimmel’s show to follow.
