The pop superstar has long campaigned for gay rights and she has been a fierce opponent of the country's controversial Don't Ask, Don't Tell (DADT) policy, which required homosexuals to hide their orientation or risk losing their job. She took to Twitter to post a picture of her smiling and holding a sign reading "Full equality," reports the Daily Express.
"Can't hold back the tears + pride. We did it! Our voice was heard + today the Senate repealed DADT. A triumph for equality after 17 years... Today I am so proud to be American. I wish I was home so I could throw a Parade. We are on the way...to full equal," the star added in a message.
Other stars have also joined the pop icon Gaga in praising the move. "Supporting all our troops!... Congrats 2 US!!! repeal of DADT & 17 years of allowing human rights violations. There's hope after all," Katy Perry tweeted.
Gay pop star Ricky Martin wrote, "One step closer to equality!! DADT is gone! Historical!"
