People

Jimmy Kimmel is taking the week off after his 7-month-old son, Billy, had successful heart surgery this morning. Tonight, Pratt fills in with guests Margot Robbie and Chris Stapleton. Billy Kimmel’s surgery was originally scheduled in late October -- when Kimmel last had guest hosts -- but was delayed due to a common cold.
