Continuing her reign as one of TV's most generous talk show hosts, Ellen DeGeneres surprised Jimmy Kimmel by dedicating a room to his son, Billy, on the heart institute floor of the Los Angeles Children’s Hospital during Tuesday's episode of The Ellen DeGeneres Show.

The gesture comes after a tearful monologue last spring in which Kimmel detailed the genetic heart condition of Billy, who has already undergone two surgeries within his 10-month life. In December, Kimmel brought his son on stage to advocate for the Children’s Health Insurance Program (CHIP).

DeGeneres previously helped raise a million dollars for the Los Angeles Children's Hospital, where Billy was treated. Several of his nurses were in the audience to witness Kimmel's surprise. "You're such a great guy, and that was so emotional to see you go through that," DeGeneres told Kimmel before unveiling the big news.

Kimmel is set to host the 2018 Academy Awards on Sunday, March 4. Watch a clip from his Ellen DeGeneres Show appearance below.
