By the end of 2009, she released her second studio album The Fame Monster, with the global chart-topping lead single "Bad Romance", as well as having embarked on her second headlining tour of the year, The Monster Ball Tour.
She is inspired by glam rock musicians such as David Bowie and Freddie Mercury, as well as pop music artists such as Madonna and Michael Jackson. She is also inspired by fashion, which she has said is an essential component to her songwriting and performances. To date, she has sold over eight million albums and 35 million singles digitally worldwide.
After The Fame was released, she revealed that the song ¨Poker Face¨ was about her bisexuality. In an interview with Rolling Stone, she spoke about how her boyfriends tended to react to her bisexuality, saying ¨The fact that I’m into women, they’re all intimidated by it. It makes them uncomfortable. They’re like, 'I don’t need to have a threesome. I’m happy with just you'.¨
When she appeared as a guest on The Ellen DeGeneres Show in May 2009, she praised DeGeneres for being ¨an inspiration for women and for the gay community¨. She proclaimed that the October 11, 2009 National Equality March rally on the national mall was ¨the single most important event of her career.¨ As she exited, she left with an exultant ¨Bless God and bless the gays,¨ similar to her 2009 MTV Video Music Awards acceptance speech for Best New Artist a month earlier.
