See How Justin Timberlake "Scarred" Mandy Moore Forever!

Justin Timberlake clearly wasn't aware of the effect he had on women back in the day.

Mandy Moore stopped by "The Late, Late Show" where she shared a story about how JT permanently scarred her when she was just a teenager.

When the "This Is Us" star was 15-years-old, she went on the road with *NSYNC and the Backstreet Boys, landing the spot as their opening act.

Though the singer-turned-actress didn't interact with the guys a whole lot, there's one conversation she had with Timberlake that has stuck with her through the years.

"I remember distinctly one time walking backstage, and I didn't really see much of the guys because I was the measly opening act," she told James Corden.

"Nobody cared about me, but Justin Timberlake and somehow there was a conversation about feet or foot size," she continued. "They were comparing shoe size. And all the background dancers and *NSYNC background dancers and my background dancers, and I stroll up at 15 like freaking out that Justin Timberlake is there."

"He was like, 'You have big feet for a girl,'" she explained. "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."

"It was embarrassing," she declared.

Although, the brunette beauty does say she wears a size 10 shoe, "but I'm 5 feet 10 inches tall."
