Stefani Joanne Angelina Germanotta (born March 28, 1986), known professionally as Lady Gaga, is an American singer, songwriter, and actress. She is known for her image reinventions and versatility in the entertainment industry. Gaga began performing as a teenager, singing at open mic nights and acting in school plays. She studied at Collaborative Arts Project 21, through the New York University Tisch School of the Arts, before dropping out to pursue a career in music. After Def Jam Recordings canceled her contract, she worked as a songwriter for Sony/ATV Music Publishing, where she signed a joint deal with Interscope Records and KonLive Distribution, in 2007. Gaga had her breakthrough the following year with her debut studio album, The Fame, and its chart-topping singles “Just Dance” and “Poker Face”. The album was later reissued to include the extended play The Fame Monster (2009), which yielded the successful singles “Bad Romance”, “Telephone”, and “Alejandro”.

Gaga’s five succeeding albums all debuted atop the US Billboard 200. Her second full-length album, Born This Way (2011), explored electronic rock and techno-pop and sold more than one million copies in its first week. The title track became the fastest-selling song on the iTunes Store, with over one million downloads in less than a week. Following her EDM-influenced third album, Artpop (2013), and its lead single “Applause”, Gaga released the jazz album Cheek to Cheek (2014) with Tony Bennett, and the soft rock album Joanne (2016). She ventured into acting, winning awards for her leading roles in the miniseries American Horror Story: Hotel (2015–2016) and the musical film A Star Is Born (2018). Her contributions to the latter’s soundtrack, which spawned the chart-topping single “Shallow”, made her the first woman to win an Academy Award, BAFTA Award, Golden Globe Award, and Grammy Award in one year. Gaga returned to dance-pop with her sixth studio album, Chromatica (2020), which yielded the number-one single “Rain on Me”. She both released her second collaborative album with Bennett, Love for Sale, and starred in the biopic House of Gucci in 2021.

Having sold an estimated 170 million records, Gaga is one of the world’s best-selling music artists and the only female artist to achieve four singles each selling at least 10 million copies globally. Her accolades include 13 Grammy Awards, two Golden Globe Awards, 18 MTV Video Music Awards, awards from the Songwriters Hall of Fame and the Council of Fashion Designers of America, and recognition as Billboard’s Artist of the Year (2010) and Woman of the Year (2015).

Stefani Joanne Angelina Germanotta was born on March 28, 1986, at Lenox Hill Hospital in Manhattan, New York City, to an upper middle class Catholic family. Both of her parents have Italian ancestry. Her parents are Cynthia Louise (née Bissett), a philanthropist and business executive, and Internet entrepreneur Joseph Germanotta, and she has a younger sister named Natali. Brought up on the Upper West Side of Manhattan, Gaga said in an interview that her parents came from lower-class families and worked hard for everything. From age 11, she attended the Convent of the Sacred Heart, a private all-girls Roman Catholic school. Gaga has described her high-school self as “very dedicated, very studious, very disciplined” but also “a bit insecure”. She considered herself a misfit and was mocked for “being either too provocative or too eccentric”.

Gaga began playing the piano at age four when her mother insisted she become “a cultured young woman”. She took piano lessons and practiced through her childhood. The lessons taught her to create music by ear, which Gaga preferred over reading sheet music. Her parents encouraged her to pursue music and enrolled her in Creative Arts Camp. As a teenager, she played at open mic nights. Gaga played the lead roles of Adelaide in the play Guys and Dolls and Philia in the play A Funny Thing Happened on the Way to the Forum at Regis High School.[11] She also studied method acting at the Lee Strasberg Theatre and Film Institute for ten years. Gaga unsuccessfully auditioned for New York shows, though did appear in a small background role as a high-school student in a 2001 episode of The Sopranos titled “The Telltale Moozadell”. She later said of her inclination towards music:
