Katherine Jenkins thinks it's an "honour" to have her face tattooed on a fan's thigh.
The 38-year-old singer - who has children Aaliya, three, and Xander, six months, with husband Andrew Levitas - was stunned when a man came to a record signing and dropped his trousers in front of her but then realised it was because he wanted to show her his unique inking, which she thinks is both "weird" and "lovely".
She said: "Firstly everybody is really lovely because I am very lucky. I do have a lovely gentleman who came to one of the record signings and he came up to the table and he said, 'Katherine I've got something to show you,' and then he dropped his trousers and I was scared to look but he actually had a big tattoo of my face on my thigh.
"It's weird but it's also so lovely. I think that's quite an honour that he wants my face [on his thigh.] He then wanted me to autograph the tattoo and I think he had the tattoo of my autograph added as well."
Despite her classical music success, the mezzo-soprano admitted she's terrible at karaoke and her husband has made her promise never to get up and sing pop songs in front of other people again because she's so "rubbish".
She told talk show host Jonathan Ross: "I'm rubbish at Karaoke. I promise you. When I first met my husband, Andrew, he came to a party and we'd had a few drinks, both of us and I thought, 'I've got this' and I sang Adele.
"And in the morning, he said to me, 'Don't ever do that again, you should never do Karaoke.' I really suck at it.
"Whitney Houston I murder as well. It's all really, really bad. I think I'm trying to sing as a pop diva and it's just not my voice and so it just really goes wrong so instead whenever I'm pushed into doing I do something more like rap. It is safer."
In order to keep her voice in good shape, Katherine goes days without speaking when she's on tour - much to the delight of her husband.
She said: "When I'm on tour I don't speak between the shows so I come off stage and I'll go for at least 24 hours of absolute silence. Not a word. It actually works.
"If you ever lose your voice, the voice is a muscle so it has to have complete rest. You can't even whisper. I mouth and expect people to lip read or expect my husband to understand me.
" He actually loves it when I'm on voice rest and he waits for the moment where I can't answer back and then he drops something that is really going to wind me up!"
The full interview airs on 'The Jonathan Ross Show' on Saturday (20.10.18) on ITV.
