And now it appears the bizarre facial feature may be spreading after she showed off her pointed shoulderblades in her latest online video.
In her latest Gagavision video on YouTube, the 25-year-old singer reclines in the bath as she talks about her bizarre philosophy.
Bizarre: Lady Gaga had horns on her face during an appearance on the Tonight Show in February
She says in the video: 'Born This Way is who I am. An artist in a constant state of half-fantasy/half-reality at all times.'
When asked what is the most personal thing she's ever told her fans, aka 'little monsters', she explained: 'The greatest challenge in writing Born This Way is I had to become confident and secure in myself.
'I had to leave my insecurity behind me�.Whatever residual scars behind. I spent two years delving deep into my wounds�the blood transfusion.'
She then turns her attention to her latest single Judas, of which she said: 'Judas leaked a slow death,' so she decided to release it earlier than planned.
Although she appeared to be 'sprouting' horns in her recent Harper's Bazaar magazine shoot, their recent appearance in her Gagavision video suggests they have been 'growing'.
In the Harper's interview, she insisted her horns were real, not prosthetics as is widely believed.
She said: 'They�re not prosthetics. They�re my bones.
'They�ve always been inside of me, but I have been waiting for the right time to reveal to the universe who I truly am. They come out when I�m inspired.
In the interview, she even suggested that her fans have the potential to grow these horn-like bones.
She continued: 'We all have these bones! They're the light from inside of us.'
Now you see them, now you don't: Gaga's horns were missing as she sat at a dressing room table
