Shawn Mendes and Jimmy Fallon argue over who Justin Timberlake likes more

Shawn Mendes and Jimmy Fallon are duking it out over a mutual friend!

The 20-year-old pop star stopped by The Tonight Show Starring Jimmy Fallon on Thursday and dished on his friendship with Justin Timberlake, who recently brought him up on stage at the iHeartRadio Music Festival.

“We’re actually pretty good friends now”, Mendes bragged to Fallon. “What’s that?” the 44-year-old late-night host questioned.

Mendes gave the same answer twice more before realizing Fallon was teasing him.

“It was the coolest thing of my entire life”, Mendes said sincerely of his performance of “What Goes Around”... with Timberlake, 37. “Who’s the better friend now?”

Fallon took the teasing well until Mendes quipped, “You follow him on Instagram, right?”

“No, I just hang out with him outside of fake social media”, Fallon shot back. “I’m really his friend”.

The pair seemed to get back on a congenial level when Fallon told Mendez that he knows Timberlake likes him. “He, does yeah. I think he does. I hope he does”, Mendes said.

“He definitely does”, Fallon assured. “I mean he likes other people too. He doesn’t like everybody”.

“He likes a lot of people”, Mendes corrected.

“Eh not really. He’s very selective, actually”, Fallon jokingly said. “The more I think about it, he only likes one person”.

Mendes went on to brag that it’s “very rare” for Timberlake to bring other singers on stage with him, before marveling at all the other singers he’s been able to work with.

“In all honesty, I got to play with him, John Mayer and Ed Sheeran within the same two years”, he said. “I mean, I’m pretty sure the first time we spoke you asked me who one of my idols was and I said Justin Timberlake”.
