Lady Gaga, Stefani Joanne Angelina Germanotta

The following single "Poker Face" was an even greater success, reaching number-one in almost all major music markets in the world, including the United Kingdom and the United States. It won the award for Best Dance Recording at the 52nd Grammy Awards, over nominations for Song of the Year and Record of the Year. The Fame was nominated for Album of the Year; it won the Grammy Award for Best Dance/Electronica Album. Although her first concert tour happened as an opening act for fellow Interscope pop group, the reformed New Kids on the Block, she ultimately embarked on her own worldwide concert tour, The Fame Ball Tour, which was critically appreciated and began in March 2009; ending in September of that year. The cover of the annual "Hot 100" issue of Rolling Stone in May 2009 featured a semi-nude Gaga wearing only strategically placed plastic bubbles.
In the issue she said that while she was beginning her career in the New York club scene, she was romantically involved with a heavy metal drummer. She described their relationship and break-up, saying of it, "I was his Sandy, and he was my Danny of Grease, and I just broke." He later became an inspiration behind some of the songs on The Fame. She was nominated for a total of nine awards at the 2009 MTV Video Music Awards, winning the award for Best New Artist, while her single "Paparazzi" won two awards for Best Art Direction and Best Special Effects. In October Gaga received Billboard magazine's Rising Star of 2009 award. She attended the Human Rights Campaign's "National Dinner" the same month, before marching in the National Equality March for the equal protection of LGBT people in all matters governed by U.S. civil law in Washington, D.C.
Written over the course of 2008–09, The Fame Monster, a collection of eight songs, was released in November 2009. Each song, dealing with the darker side of fame from personal experience while she traveled the world, is expressed through a monster metaphor. Its first single "Bad Romance" topped the charts in eighteen countries, while reaching the top-two in the United States, Australia and New Zealand. In the U.S., Gaga became the first artist in digital history to have three singles (along with "Just Dance" and "Poker Face") to pass the four million mark in digital sales. The song won a Grammy for Best Female Pop Vocal Performance while its accompanying music video won the Grammy Award for Best Short Form Music Video.
The album's second single "Telephone", which features singer Beyoncé, was nominated for the Grammy Award for Best Pop Collaboration with Vocals and became Gaga's fourth UK number-one single while its accompanying music video, although controversial, received a more positive reception from contemporary critics: praising her for "the musicality and showmanship of Michael Jackson and the powerful sexuality and provocative instincts of Madonna". Her following single "Alejandro" paired Gaga with fashion photographer Steven Klein for a music video similarly as controversial—critics complimented its idea and dark nature, but the Catholic League attacked Gaga for her alleged use of blasphemy. Despite the controversy surrounding her music videos, they made Gaga the first artist to gain over one billion viral views on video-sharing website YouTube.
