The 'Bad Romance' singer landed by private plane and reportedly gave photographers and waiting fans a five-minute performance outside.
Sporting long curled blonde locks and flawless sun-kissed make-up, Gaga looked she was on a catwalk as she kept a very composed face.
The 28-year-old, who is dating Chicago Fire actor Taylor Kinney, finished off her look with a pink mesh wraparound skirt and towering platform heels encrusted with diamonds - seriously bling but how does she manage to walk in them?!
Gaga was treated like royalty and was cheered by fans as two topless hunks carried her into the entrance of a central Athens hotel.
Gaga arrived in Greece to perform at the Athens Olympic Stadium on Friday as part of her 'artRave: The ARTPOP Ball' tour.
Taking to Instagram after her arrival, Gaga said: "Ela Greece. The Goddess of Love is here. Get ready to rave Olympus. #artraveAthens."
It seems Gaga was in love with her hotel room too, and soon enough she went on an Instagram photo spree.
In one snap, Gaga covers her bare assets with her hands and lays provocatively across a marble chair while claiming that she's "feeling frisky".
In another shot, she flaunts her bare bottom while posing in front of a running bath. Commenting on the photo, she said: "Bathtime. 'The Royal Suite' fit for a Goddess, or you know, a downtown New York gal with big dreams, and a lotta nerve."
Elsewhere, Gaga celebrated the launch of her new perfume Eau de Gaga this week by releasing some saucy campaign pictures of herself being surrounded by semi-naked men.
