The star, clearly as body confident as ever, left little to the imagination as she arrived at the Belgium jazz club L’Archiduc in a revealing sheer frock, leaving her bare breasts and tiny thong on full display.
The five-time Grammy award winner seemed unfazed by her revealing outfit and oozed confidence as she made her way through the crowds and into the venue.
In typical Gaga fashion, the star teamed her ensemble with a huge curly black wig and towering peep-toe heels.
The night out was the official after-party for Mother Monster’s concert with Tony Bennett, and the 88-year-old music legend followed closely behind her, clearly relishing in the attention.
Speaking about working with the famous star, Gaga revealed that her zest for music was brought back to life thanks to his input.
She said: “I feel happier. I was starting to think there was no elegance left in this industry, no charms. I though there was no gravity, no authenticity. And then I worked with Tony.
She added to The Wall Street Journal: “When I walked into the studio, everyone stood up for me and he was always dressed so beautifully and told me I looked lovely.
Meanwhile, it has been revealed that Barbra Streisand is the latest music veteran to want to collaborate with the star.
According to Page Six, Barbra and her musical peer Elton John are both keen to create a similar record to Gaga’s collaboration with Bennett.
It is believed that the pair have contacted Gaga to see if she’s available to sing duets with them
