During last tenebrousness’s ITV special An Evening With Take That, Natasha, a fan of the band, confronted Gary, 46, with the upsetting inking.
She asked him if he remembered signing her wrist with a Sharpie a few months in the past.
The Rule The World singer responded: «Yeah… you didn’t get it tattooed, did you?»
Natasha celebrated that she had, before holding out her arm to reveal the tattoo, which read «Gay» rather than of Gary.
Examining his artwork, he explained: «Oh goodness, I think I remember hint to you ‘please don’t get that tattooed’.
«I’m embarrassed to say I was feeling lazy that day and I perfectly wrote ‘Gay’.»
«But I made up for it because I put a kiss underneath. I don’t do that very habitually,» he added in his defence.
Gary agreed to make up for the funny mistake by augmenting something else to the tattoo.
Bandmate Mark Owen cheekily suggested that possibly an «R» would be appropriate.
Gary and Mark were also joined by closing member Howard Donald for the one-off TV show, which saw the group do their best hits to a studio audience.
