Justin Timberlake and Mandy Moore have a long history together.

At the time, Moore was a 15-year-old pop star and was touring with the Backstreet Boys and ‘NSync.

“I’m a terrible dancer, but I had background dancers at the time because that’s what you did, and I remember distinctly one time walking backstage, and I didn’t really see much of the guys because I was the measly opening act,” Moore said to The Late Late Show host, James Corden.

“Nobody cared about me. But Justin Timberlake was there and somehow there was a conversation about feet or foot size. They were comparing shoe [size]. And all the background dancers and the ‘NSync background dancers and my background dancers [were there], and I stroll up at 15, like, freaking out that Justin Timberlake is there.”

And that’s when it happened. Timberlake said something to Moore that would haunt her for years to come.

“He was like, ‘You have big feet for a girl’,” Moore said to Corden.

“I’m sure he doesn’t remember this at all but I was so impressionable, and I thought the world of him and he was on a pedestal. I mean, 16 years later it stuck with me, so it really scarred me emotionally.”

Oh, and in case you’re wondering, Moore’s feet are a size 10.
