If you're anything like us, the one question that comes to mind is simply Why? And luckily — a whopping 66 weeks after she shared the ink on Instagram — she finally revealed on Late Night with Seth Meyers that the idea came to her and her bandmates when they were on tour 10 years ago.“Their one rule was nobody was allowed to do...that thing in the shower,” she said, hinting to Meyers that she was referring to masturbating. “It became this big joke, because one of my band members was like, ‘I don’t want babies on my feet.' And so we created a song called ‘Babies on My Feet’ that we sang on stage every night. No one had any idea what we were talking about.”And that's how it all started. Once the tour wrapped, the entire band got tadpoles tattooed to pay tribute to the memories they had shared. It's actually quite sweet, if you can get over the fact that your birds-and-bees chat might come way ahead of schedule, should you have offspring. As for us, we'll be following Moore's lead and sticking to original, meaningful ideas before hitting up the parlour, too.
