UPDATE (3/13/15, 1:30 p.m. ET): Snooki posted the photo below, which clearly shows her hair isn't green. We'll wait for your next new look, N!

It's almost time to break out the shamrocks, pour some Guinness and don green attire to celebrate the memory of Patrick, the patron saint of Ireland. So has Snooki -- who is known for getting into the holiday spirit with her fam for just about any special day -- changed her hair for the leprechaun-themed occasion?

The (possible) evidence: The mother of two shared this somewhat mysterious Instagram snapshot, which features her wedding bling front and center:

But the bigger question: Does Nicole's long, wavy 'do have emerald highlights? The "Jersey" girl is known for dying and chopping her strands and going for fresh looks, so it's very possible that it's a hint of jade.

Or is it Mrs. LaValle's usual black hue -- and it's just the lighting in the pic that's giving her locks a certain tint? It could also be an Insta filter giving the illusion that it's a different shade. After all, the erstwhile "Snooki & JWOWW" star simply captioned the pic "wifey" with a diamond emoji, and there are no possible clues on any other social media channels...
