The American Horror Story actress was so happy with Clinton’s nomination by the Democrats that she stripped.
Gaga posted a picture on Instagram of her in a stars and stripes bather, lounging next to her guitar.
The Applause singer says: “Nothing can keep a strong woman down. VOTE for the first female president in history. Shake it up America, this country needs a little rock n roll.”
Gaga, 30, joins celebs George Clooney, Britney Spears and Khloe Kardashian who all publicly support Clinton.
Clinton’s rival, controversial Republican candidate Donald Trump, also has a few celebs in his corner.
Hulk Hogan, Mike Tyson, Kirstie Alley and Stephan Baldwin are all Trump supporters.
Even rapper Azealia Banks doesn’t mind Trump becoming her commander-in-chief, although some might think her reasons for supporting him borders on insanity.
She recently tweeted: “Trump is evil like America is evil and in order for America to keep up with itself it needs him.”
Hollywood has always had close ties with the White House, even back in the day of JF Kennedy and Marilyn Monroe.
And when Barack Obama was inaugurated in 2009, stars like Beyoncé, Katy Perry and Oprah all threw their weight behind him.
