The singer celebrates Halloween with her friends wearing an unusual green outfit.
Lady Gaga went topless as she celebrated Halloween with her friends this week.
The 'Born This Way' star flashed the flesh as she joined make-up artist Tara Savelo to celebrate the spooky holiday.
Lady Gaga, whose green outfit featured well-situated pieces of fabric and glitter that helped protect her modesty, looked to be in high spirits in pictures posted on her Little Monsters website.
The star later described her outfit on Twitter as the "best costume ever".
Earlier this year, Lady Gaga announced plans to launch a Body Revolution campaign following press coverage of her recent weight gain.
Speaking about the reports in an interview with Stylist, the 'Judas' singer admitted that everyone was telling her about her weight gain – but that she was not bothered.
Lady Gaga posted pictures from her Halloween celebrates on her social networking website, Little Monsters:
"I was acutely aware of some photos on the internet - my mum called me and was like, 'Did you gain weight?'" she said.
"Everybody was telling me about it, and I didn't really care."
Meanwhile, Lady Gaga is set to resume her 'Born This Way Ball' world tour in South America tomorrow night (3rd November).
The singer's second major world tour has already seen her perform at venues across Europe and the Far East.
