American singer Lady Gaga has embarked on five concert tours and performed live at various award ceremonies and television shows.
 Gaga promoted her debut single "Just Dance" through performances at several award ceremonies and television shows, including Miss Universe 2008 and "So You Think You Can Dance".
 She first served as an opening act for the boy band New Kids on the Block and the girl group The Pussycat Dolls, before beginning her own headlining tour, The Fame Ball Tour, which began in March 2009 and ended in September 2009.
 Following the canceled tour with rapper Kanye West, Gaga embarked on her second worldwide concert tour The Monster Ball Tour.
 Staged in support of her extended play "The Fame Monster" (2009), the tour was critically acclaimed and grossed $227.4 million, making it one of the highest-grossing concert tours of all time.
 Gaga also performed songs from the album at award ceremonies—the American Music Awards of 2009, 52nd Annual Grammy Awards and 2010 Brit Awards.
 At the 2010 "Billboard" Touring Awards, Gaga won the Breakthrough Performer Award, as well as the Concert Marketing & Promotion Award.
Lady Gaga: Queen of Pop is a biography of American singer Lady Gaga.
 It was written by Emily Herbert (pen name for Virginia Blackburn) and published in the United Kingdom by John Blake Publishing Ltd. The book was published by Overlook Press in the United States with the title Lady Gaga: Behind the Fame.
 Additional versions under the title "Lady Gaga: Queen of Pop" were published in 2010 by Wilkinson Publishing of Melbourne in Australia and by Gardners Books in the United Kingdom.
 The book discusses Gaga's early life when she was known as Stefani Joanne Angelina Germanotta from her birth in 1986, and chronicles her education at Convent of the Sacred Heart in New York, her early visits to nightclubs with her mother to perform at open-mic events, and her brief foray into the Tisch School of the Arts, leading up to her first experience of fame.
 Germanotta took the name "Lady Gaga" from the song "Radio Ga Ga" by the rock group Queen; she released her first album "The Fame" in 2008.
 "Lady Gaga: Queen of Pop" describes the musician's success in the industry, noting her business collaborations and appearance on the cover of "Rolling Stone" in 2009.
"Bad Romance" is a song by American singer Lady Gaga from her third extended play, "The Fame Monster" (2009).
 It was written and produced by Gaga and RedOne.
 Lyrically, "Bad Romance" explores Gaga's attraction to individuals with whom romance never works, her preference for lonely relationships and the paranoia she experienced while on tour.
 Following an illegal demo leak, Gaga showcased the final product at Alexander McQueen's show at the Paris Fashion Week in October 2009, followed by the release of the single's cover art.
 Musically, "Bad Romance" features a spoken bridge, a full-throated chorus and sung lyrics about being in love with one's best friend.
 The song, which is imbued with elements of Germanesque house and techno, as well as music from 1980s and the 1990s, was touted by Gaga as an experimental pop record.
 The song contains a few lines in French.
American singer Lady Gaga has released three video albums and has been featured in twenty-eight music videos.
 From her debut album "The Fame" (2008), she released music videos for the singles "Just Dance", "Poker Face", "LoveGame" and "Paparazzi".
 In the latter, she portrays a doomed starlet taking revenge on her lover.
 She reissued her first album as "The Fame Monster" (2009), preceded by a music video for the lead single "Bad Romance", which won a Grammy Award for Best Music Video and seven MTV Video Music Awards, including Video of the Year in 2010.
 The following year, Jonas Åkerlund directed the music video for "Telephone"—a continuation of "Paparazzi"—which was shot as a short film.
 The video received an MTV Video Music Award for Video of the Year nomination, and was named the Best Music Video of the Decade by "Billboard" in January 2015.
 For her 2010 video "Alejandro", Gaga received positive review from critics, though she was criticized by the Catholic League that alleged blasphemy.
"Monster" is a song by American singer Lady Gaga from her third extended play (EP), "The Fame Monster" (2009).
 Inspired by her "Fear of Attachment Monster", the record was written by Gaga, RedOne and Space Cowboy, with RedOne producing the track.
 Gaga had explained that "Monster" describes her fear of sex and relationships, and described the lyrics as being in love with the bad boy all the time, but instead of running away, one keeps going back to the same person.
 She added that the fear in "Monster" erupted from her need to have a stable relationship.
 Incorporating the usage of heavy bass lines, descending keyboard lines and "massive" choruses, "Monster" contains zombie-like metaphors and a reference to Gaga's debut single "Just Dance".
Fame Kills: Starring Kanye West and Lady Gaga was a planned co-headlining concert tour by American rapper Kanye West and singer Lady Gaga.
 For the tour, which would have supported West's fourth album "808s & Heartbreak" (2008) and Gaga's "The Fame Monster" EP (2009), the pair conceived a production that would unite their different musical audiences.
 The tour was scheduled to run from November 2009 to January 2010, but was canceled after public controversy regarding West's interruption of Taylor Swift's Best Female Video speech at the 2009 MTV Video Music Awards.
 Shortly after the cancellation, Gaga embarked on her own tour, The Monster Ball Tour, while West took a break from his career.
Just Dance is a rhythm game series developed and published by Ubisoft.

"Paparazzi" is a song by American singer-songwriter Lady Gaga from her debut studio album, "The Fame" (2008).

 Musically, it is an uptempo techno-pop and dance-pop song whose lyrics describe a stalker following somebody to grab attention and fame.
"Judas" is a song by American singer Lady Gaga, from her second studio album, "Born This Way" (2011).
 It was released four days ahead of schedule by Interscope Records on April 15, 2011.
 Written and produced by Lady Gaga and RedOne, "Judas" is a dance and electro house song about a woman in love with a man who betrayed her.
 It embodies the incidents that have haunted Gaga in the past, and its core meaning refers to the negative parts of her life that she cannot escape.
 Gaga has further explained that the song was also about honoring one's inner darkness in order to bring oneself into the light.
 The artwork for the single was designed by Gaga in Microsoft Word.
 In spite of a polarizing impact on several religious groups, the song was generally well received by critics, who likened the song to "Bad Romance" with some noting it should have been the album's lead single.
