It's Lady Gaga!
Yep, another day, another topless Gaga pic.
"Oi, galera! [Portuguese for 'Hey, guys'] In Rio, and my beautiful fans are wearing leather and bandanas in the sun — badasses, gorgeous smiles, and fists in the air! I hear you!" she tweeted that day, adding, "Brazil, there's hundreds at [this] hotel, and this is what the f—k it’s all about: revolution through music. Get ready to party at the show in two days."
She also sent hamburgers, fries, and soda to the throng of fans gathered outside the hotel.
