The 26-year-old singer, who has never been shy about her support for gay, bisexual and transgender rights, arrived in the historic city for a performance and was welcomed by a mob of fans at the airport, reported Daily Mail.
"Just arrived in St Petersburg Russia. I'm so delighted to see so many monsters at the airport. Take me to the ballet. Thank You Prime Minister Medvedev for not standing by your party's anti gay propaganda law and instead supporting my show and fans all over Russia.
"Prime Minister Medvedev please accept my gratitude I am looking forward to performing in Russia and celebrating our cultures coming together," she tweeted.
