Indeed, if you look very, very closely, you can see a bit of glare in the middle of her ring finger when she bends it around the microphone, and that's exactly where the "Pete" tattoo used to be. And yes, it does look like there's a band-aid there. Since covering it up with makeup would have been a more effective way to make it invisible, it's more likely a last-minute fix or remnants from a fresh tattoo cover-up. Or, maybe she just cut her finger slicing vegetables at the worst possible time and this is all just a big misunderstanding (maybe). It's still too early to tell.
