The Ellen DeGeneres Show has set a special tribute to its host's most important episode of television.
The syndicated talk show will dedicate its entire April 28 hourlong episode with a special star-studded tribute to the April 30, 1997, "The Puppy Episode" of her former ABC sitcom Ellen.
The two-part episode aired 20 years ago and helped usher in a more inclusive era of television. The season four episode featured DeGeneres' character coming out as gay and aired in tandem with the comedian-turned-actor-turned-host's personal declaration on the cover of Time magazine. The issue ran with a photo of DeGeneres and her quote "Yep, I'm Gay."
The Ellen DeGeneres Show will celebrate the milestone with a reunion with special guest stars Oprah Winfrey and Laura Dern joining castmembers Joely Fisher, Clea Lewis and David Anthony Higgins. It marks the first reunion since the ABC sitcom ended.
The tribute will also feature messages from celebrities and real-life stories of how the episode impacted fans, viewers and the LGBT community.
