I love Lady Gaga,  Stefani Joanne Angelina Germanotta (born March 28, 1986), known professionally as Lady Gaga, is an American singer, 
What is her genre of music?
She's  all weather,  follow-up EP, "The Fame Monster" (2009), featuring the singles "Bad Romance", "Telephone", and "Alejandro", also proved successful.
That is great. i am a great fan of  "Alejandro".
I love the fame,  She rose to prominence the following year with her debut album, a dance-pop and electropop record titled "The Fame"
She must have ascended to fame quite fast. Now she is a household name.
Oh yeah,  Its title track also became the fastest selling song on iTunes with over a million downloads 
Really.! I guess a million downloads translates to many dollars as well.
Exactly,  the album really topped the US charts
Her versatility in terms of genre will take her to places and will also keep her relevant in the industry for ages
