Remember in 2010 when Rihanna dyed her hair red and so did the entire female population of the UK?
Well, ever since the 28-year-old revealed a huge inking on her chest, tattoo artists have seen a massive increase in customers requesting tats on their undertits.
The latest tattoo trend - which I'm aware has actually been around for centuries and wasn't invented by Riri before you bore me in the comments - has even got its own hashtag on Instagram. Here's a bunch of undertit tats.
What do you reckon, lads? Could you be tempted into a bit of under titty tatting?
