Gaga covered her assets with a skimpy shell bra and a pair of thongs. Two men carried the 28-year-old singer to stage. Gaga coupled her racy look with a fish net bra designed by Turkish designer Zeynep Tosun and a 9-inch platform heels.

Gaga also took to Twitter to express her gratitude to the people of Athens for a warm welcome.

"Thank you for the beautiful warm welcome Athens," she tweeted, adding, "We come in the spirit of love, music, and to celebrate your beautiful history. Where classical art began. We belong together."
