Does Lady Gaga have plastic surgery?

Controversial Lady Gaga has sparked speculation she has undergone a nose job, after it appeared more streamlined at a recent event.

Recently Lady Gaga’s nose appeared to be slimmer and smaller.

A spokesperson for the singer refused to comment on the claims.

Lady Gaga has spoken out about her looks and in a past interview claimed she would never go under the knife.

Speaking to Harper’s Bazaar in 2011 after sporting prosthetic horns and claiming they were her “bones”, Lady Gaga said: “I have never had plastic surgery, and there are many pop singers who have.”

“I think promoting insecurity in the form of plastic surgery is infinitely more harmful than an artistic expression related to body modification.”

She continued: “And how many models and actresses do you see on magazine covers who have brand-new faces and have had plastic surgery, while I myself have never had any plastic surgery?”

While Lady Gaga’s looks might be causing controversy, her absence from social networking sites has also raised eyebrows.

The singer, who has over 39million followers on Twitter, recently announced she was leaving the site – albeit for a temporary period.

Lady Gaga has changed her profile picture to the default egg and has written: “This interface has been shutdown temporarily. Please check back for updates.”

It’s thought Lady Gaga’s departure from Twitter is to coincide with the promotional drive for her new album ARTPOP.
