Lady Gaga has been revelling in her own birthday celebrations on twitter.

The 'Born This Way' hitmaker turned 26 today (28.03.12) and she took to her social networking account to cryptically reveal she feels like a 15 year old.

Responding to a fan who asked how she is going to celebrate her big day, Gaga replied: "Quinceanera."

The word means "one who is 15" in Spanish and it can also translate to be "Fiesta de Quincea?era", which is the celebration of a girl's 15th birthday in parts of Latin America.

Shortly before she turned 26, Gaga posted a picture of a half-eaten birthday cake with a candle in, and she wrote accompanying message: "This is how it feels turning 26 in three and a half hours. Ha! (sic)".

Last year, Gaga - whose real name is Stefani Germanotta - was presented with a custom-made sex doll at her 25th birthday party with family and close friends Kate Hudson, Fergie, Cindy Crawford and Adam Lambert at Los Angeles' LA Cita Mexican restaurant.

The singer also wished herself a happy birthday on twitter and posted a picture of a message she wrote with a crayon on a napkin, and she praised her fans for their support.

She tweeted: "Drawing on table at restaurant. If I had to give it all back, but got to keep my fans, that'd be ok.

"You are all the present I need in the world. (sic)"
