Mandy Moore was left "emotionally scarred" by Justin Timberlake when he told her she had big feet.
The 32-year-old singer and actress started out her career at the young age of 15 when she went on tour with Justin's former band NYSNC, and has revealed that a conversation she had with the 35-year-old has haunted her ever since.
Appearing on The Late Late Show with James Corden, the Tangled actress said: "I had background dancers at the time because that's what you did. I remember distinctly one time walking backstage and I didn't really see much of the guys because I was just the opening act, nobody cared about me.
"But Justin Timberlake was there, and there was a conversation about feet or foot size, they were comparing shoe sizes. And all the background dancers were there, the NSYNC background dancers and my background dancers.
"And stroll up at 15, freaking out that Justin Timberlake is there and he's like 'You have big feet for a girl'."
The This Is Us star doesn't hold it against the Can't Stop the Feeling hitmaker as she's sure he can't recall the incident, but admits she still thinks about what he said.
She continued: "I'm sure he doesn't remember this at all, but I was so impressionable and I thought the world of him. He was on a pedestal, and I mean 16 years later it's stuck with me. It really scarred me emotionally."
Actor Matthew Broderick - who was also appearing on the show - asked the star how big her feet were, to which she said she wore a size 10 shoe, but it was balanced out by her height.
She said: "Size 10, but I'm 5'10" so [it works out]. But I was going through puberty at the time, you know what I mean? It was embarrassing."
