Am I totally out of the loop? Who the crap is Lady GaGa? The first time I’d ever heard of her was when she performed on So You Think You Can Dance. When she took the stage, I just kept thinking – who is this person!?

Here’s what I found on Wikipedia:

Stefani Germanotta (born March, 1986), better known by her stage name Lady GaGa, is a singer-songwriter dance-pop, electronica musician signed to Interscope Records. On April 8, 2008, she released her first single “Just Dance“.

As a child Lady GaGa attended the Convent of the Sacred Heart School. Having learned piano by ear at the age of 4, Lady GaGa went on to write her first piano ballad at 13 and began performing at open mike nights by the age of 14. At the age of 17 she gained early admission to the Tisch School of the Arts at NYU, where she studied music. By age twenty she began writing songs for Interscope Records artists, such as the Pussycat Dolls, also she recently declared that she wrote two songs for the upcoming Britney Spears album. She performed at the Miss Universe 2008 pageant in Vietnam, singing her debut single, “Just Dance”. On July 31, 2008, she performed “Just Dance” live on the results show of Fox’s So You Think You Can Dance. In a recent interview with TL3 Magazine she stated that she had experimented with LSD while at NYU but no longer uses any illegal substances.

In an interview with HX Magazine, she recently came out as bisexual.

Here she is yesterday arriving at MTV’s TRL in Manhattan.
