Stefani Joanne Angelina Germanotta (/ ˈ s t ɛ f ən i ˌ dʒ ɜːr m ə ˈ n ɒ t ə / ⓘ STEF-ən-ee JUR-mə-NOT-ə; 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. “No matter gay, straight, or bi, lesbian, transgendered life, I’m on the right track, baby,” Gaga sings—and Siwa, her later posts confirmed, was announcing herself as being somewhere on that list.
