The 23-year-old pop star had a relaxing two-day break on a beach in New Zealand following two performances in Auckland, but refused to tone down her eccentric dress sense.
Jason Schwarz, general manager of Waiheke's Goldwater Estate on Waiheke Island, said: "She's pretty eccentric, she didn't take her heels off once.
"She went down to Onetangi Beach to go fishing in her eight-inch heels, undies and a man's business shirt - that's it. She still had her bright yellow hair."
Discussing reports the 'Telephone' hitmaker was exhausted following her Auckland shows after she took off her headgear and lied down during her final performance of 'Bad Romance', Jason claimed she was fine, although a little tired when she arrived on the island by helicopter as she had been up partying until 4am.
He told the New Zealand Herald newspaper: "I think she was OK though, she was just pretty tired."
The New York-based performer travelled to the island with some dancers and her bodyguard, where they all enjoyed barbecues with sausages, oysters and local tarakihi fish.
Gaga is now in Australia on the latest leg of her 'Monster Ball Tour', before she heads to Japan in April.
