Stefani Joanne Angelina Germanotta (born March 28, 1986, height 5' 1" (1,55 m)), better known by her stage name Lady Gaga, is an American pop singer-songwriter. After performing in the rock music scene of New York City's Lower East Side in 2003 and later enrolling at New York University's Tisch School of the Arts, she soon signed with Streamline Records, an imprint of Interscope Records. During her early time at Interscope, she worked as a songwriter for fellow label artists and captured the attention of recording artist Akon, who recognized her vocal abilities, and signed her to his own label, Kon Live Distribution.
Gaga came to prominence following the release of her debut studio album The Fame (2008), which was a critical and commercial success and achieved international popularity with the singles "Just Dance" and "Poker Face". The album reached number one on the record charts of six countries, topped the Billboard Dance/Electronic Albums chart while simultaneously peaking at number two on the Billboard 200 chart in the United States and accomplished positions within the top ten worldwide. Achieving similar worldwide success, The Fame Monster (2009), its follow-up, produced a further two global chart-topping singles "Bad Romance" and "Telephone" and allowed her to embark on her second global concert tour, The Monster Ball Tour, just months after having finished her first, The Fame Ball Tour. Her second studio album Born This Way, released in May 2011, topped the charts in all major musical markets, after the arrival of its eponymous lead single "Born This Way", which achieved the number-one spot in countries worldwide and was the fastest-selling single in the history of iTunes, selling one million copies in five days.
Inspired by glam rock artists like David Bowie, Elton John and Queen, as well as pop singers such as Madonna and Michael Jackson, Gaga is well-recognized for her outré sense of style in fashion, in performance and in her music videos. Her contributions to the music industry have garnered her numerous achievements including five Grammy Awards, among twelve nominations; two Guinness World Records; and the estimated sale of 15 million albums and 51 million singles worldwide. Billboard named her the Artist of the Year in 2010, ranking her as the 73rd Artist of the 2000s decade.
