WATCH: Chris Pratt Prepares to Guest Host Jimmy Kimmel Live!
Jimmy Kimmel is taking another leave from his late-night talk show on ABC. Kimmel’s seven-month-old son underwent a second surgery to repair his heart. This week, his celebrity friends will take the reins of Jimmy Kimmel Live. Guest hosts are Tracee Ellis Ross, Neil Patrick Harris and Melissa McCarthy. Chris Pratt hosted the show last night, but before the show started, he needed one very important man's approval.
