Late night talk show host Jimmy Kimmel’s 7-month-old son, Billy, underwent a successful second round of surgery on Monday.
ABC announced the surgery in a statement, and said he will take time off from "Jimmy Kimmel Live" to be with his family.
Celebrities such as Chris Pratt, Tracee Ellis Ross, Neil Patrick Harris and Melissa McCarthy will be filling in for Kimmel over the next few days.
Very thankful to Chris @PrattPrattPratt for filling in for me tonight with guests @MargotRobbie & @ChrisStapleton. You are Lord of Stars on the screen and off. @JurassicWorld #FallenKingdom— Jimmy Kimmel (@jimmykimmel) December 5, 2017
Billy was originally scheduled to have the surgery in October, but the procedure was postponed because the presence of the common cold in the Kimmel household made doctors wary.
Kimmel's wife, Molly McNearney, gave birth to the baby boy on April 21. Billy had heart defects that required immediate surgery after his birth, and a second surgery months later.

The experience pushed Kimmel to become more political and get into the discussion of healthcare in the United States.
In May, Kimmel delivered a heartfelt monologue speaking about his son’s heart condition and mentioned President Trump’s plan to cut funding from the National Institute of Health, which was blocked by Congress.
“More than 40 percent of those impacted by the cuts would be children,” Kimmel said.
“If your baby is going to die -- and it doesn't have to -- it shouldn't matter how much money you make. I hope you never have to go there but if you do you’ll see so many kids from so many financial backgrounds being cared for so well with so much compassion,” Kimmel continued.

Sen. Bill Cassidy, R-La., appeared on the show in May and the two spoke about healthcare in the U.S.
Kimmel said Cassidy coined the term "the Jimmy Kimmel test," which was summed up by the late night host as: No family should be denied medical care, emergency or otherwise, because they can’t afford it.
They agreed the Jimmy Kimmel test would mean no lifetime caps, Kimmel said.
In September, Kimmel blasted Cassidy for his co-authored health care bill with Sen. Lindsey Graham, R-SC, which would have undone central components of ObamaCare and replace it with federal funds to the states.

Kimmel said Cassidy was “not very honest” and “lied to my face.”
Cassidy fired back that Kimmel does not understand.
“Jimmy doesn’t understand, not because he’s a talk show host -- because we’ve never spoken,” Cassidy told “Fox and Friends.” “He’s only heard from those on the left who are doing their best to preserve ObamaCare. He’s not heard from me, because we’ve not spoken.”
On September 26, the Senate decided not to vote on the bill.
