Italian-American singer and entertainer Lady Gaga is rather famous for... well... eccentric style and fashion statements!

There is very little she can claim she has not done... especially when it comes to experiment with hairstyles and costumes!

Her most recent escapade is going all-natural - the singer has posted photographs of herself, sans make-up, on her Twitter account.

The singer, affectionately called Mother Monster by her fans, posted the photo with the following message: "Have a beautiful day!!"

Lady Gaga is an avid Twitter user and often uses the popular social networking service to keep her fans updated on the latest in her life and career. She is, at the moment, gearing up for the forthcoming "Born This Way" tour, scheduled to start next month.
