Get ready for your Saturday morning "I'm not crying, you're crying" moment. Michael Buble cruised around with James Corden for a special Carpool Karaoke segment that aired Friday, part of the UK's "Stand Up to Cancer" telethon, HuffPost reports. And while the song-filled drive with the 43-year-old crooner and 40-year-old Late Late Show host was filled with plenty of laughs—during a conversation about his weight loss, for instance, Buble noted: "I feel like when you're smaller, your penis looks bigger"—the tone turned much more serious when it came to the subject of Buble's 5-year-old son, Noah, who's now in remission from liver cancer. "It's essentially … everybody's worst nightmare," Corden acknowledged about what Buble and his family have gone through over the past couple of years while dealing with Noah's illness.
"It's so painful to talk about," Buble said, adding that when he and his wife got the diagnosis on Noah, then 3, in 2016, "my whole life ended." Struggling as he recalled his experience, Buble said "we took it day by day" and revealed that to this day, "I'm not OK." He said that while they were going through chemo and all of the other treatments, he was the strong one, but as soon as doctors said his son would be OK, "I just fell. My wife picks me up now." He says he tells his son that while fictional characters like Superman and Spiderman are "amazing," they're also "fake. They're not real. You're a superhero. You're my hero, my real superhero."
