Alexa Ray in 2008 vs. 2014

Believe it or not, that's the same person in the two photos above.

"On a personal (and slightly ridiculous note): I would just like to add that all of the continuously-circulating rumors that I have had extensive 'face-work' and undergone breast-augmentation surgery is simply and entirely 100% false," she wrote on her Instagram account Wednesday.

"The only thing I have ever had done is my nose, which I have always been completely candid, honest, and open about- and I can swear on my Beloved Gypsy-Stella The Cat that this is the whole truth and nothing but the truth, so help me God! (But hey, there could be worse rumors circulating, so, I'll take it). Any visibly-positive alterations in terms of my public-image are an absolute and sole credit to my brilliant makeup-artist and stylist, @darlingcait … Who is a true beauty-wizard and visionary.

"(That, combined with the fact that I actually have a hearty dose of self-confidence now- which took me a little extra minute or so to find.) ; ) But hey, wouldn't it be nice if the press could just focus on my music and stage-presence? Because, honestly, I would rather be judged, critiqued, and picked apart for my actual work. So, on that note… Please join me for an intimate evening of music, martinis, [and more!] at the Cafe Carlyle- get your tickets now- the shows are almost all sold-out!!!!!!"
