We've seen Lady Gaga get a lot of tattoos to signify important moments or successes in her career - but the latest one is in a less conventional place.
In honour of her album 'The Fame Monster' turning 5 years old yesterday, Gaga got herself a big new tattoo - that seems to start near her armpit.
Gaga has yet to post a photo of the finished result, but from the pictures she posted on her Instagram during the process you can see that it stretches from her under-arm down her side, and features "Mother Monster" written in calligraphy.
Gaga posted a video on Instagram with the caption "Happy Birthday The Fame Monster" tagging tattoo artist Eric Gonzales.
This is Lady Gaga's seventeenth tattoo; she has plenty of others celebrating releases such as 'Born This Way', 'ARTPOP', as well as others in honour of her 'Little Monsters'. Interestingly, all her tattoos are on the left side of her body - keeping her right profile tattoo free, apparently at the request of her father.
She's going to run out of space soon.
