Niall Horan and Lewis Capaldi are going to have a heck of a time on tour next year.
The two mates have already started ribbing one another in interviews.
Capaldi cast the first stone earlier the night of Z100's JingleBall, claiming his Irish pal experiences flatulence at least "400 times" per five minutes.
"If I do 400 times in five minutes, then he does 7,000 times..." Niall shot back, during a chat with Danielle Monaro and Gandhi from the Mercedes-Benz Interview Lounge.
Later, after noticing Capaldi lurking nearby, Horan suggested the Scotsman "hasn't had a shower in seven days, eight days."
Gandhi then noted that, contrary to Capaldi's earlier comments, Horan smelled great.
The 'Nice To Meet Ya' tour with Niall, Capaldi and Fletcher comes to North America in April.
"We're going to have a lot of fun by the sound of it," Niall added.
You can see Niall on TV Saturday, December 14, when he drops by Saturday Night Live as the show's musical guest.
