She spends her entire life showing off her quirky - and, let's face it, sometimes scary - style creations, so when it came to Halloween, Lady Gaga was always going to have to pull out all the stops.
And that she did, "pulling out" her breasts at the same time...
The singer looked a bit like The Little Mermaid on acid (if you can imagine a Disney character being in such a state), wearing a fluoro green wig and matching tutu skirt, with her boobs covered with sparkly... cannabis plants?
Gaga took her gaga costume out for a Halloween party with her friend and makeup artist Tara Savelo, who uploaded the pic to Twitter.
What do you think of Lady Gaga's Halloween look? Tutu much, or totally buff?
