Last night, the American E! News website posted exclusive new photos a Henna-inspired design that covers most of the Kiwi design.
The site reported that Rihanna's new tattoo was "incorporated" into the Maori designs by American tattooists Bang Bang McCurdy and Cally-Jo over a session lasting 11 hours.
McCurdy told the website: "She had something pre-existing on her hand, so it was a little bit of a cover up. But also making it look good, wanted to make sure it flowed. We needed to work with what she already had."
He said it had been difficult to mix the new design.
"We were trying to fit the body with what she already had - mend the two styles with a new style."
Taylor said last night he did not want to talk about his design being covered up; saying: "We don't speak to anyone. If I was a gynaecologist and I'd just seen [former supermodel] Rachel Hunter, would I be a professional if I spoke to you?"
The tattooist has previously said how proud he was to have worked on the singer and has posted photos of the work on his Facebook page.
The week he tattooed Rihanna, he wrote: "The most important thing is that she made all the design decisions ..."
