According to the Mail Online, this could have been caused by the ancient Chinese practice of “cupping” which can help everything from muscle pain to cellulite.

Gaga was joined on the outing by her fiancé Taylor Kinney, who proposed to her on Valentine’s Day.

The hitmaker shared the happy news at the time with her millions of fans via her Instagram page, alongside a snap of her huge, heart-shaped sparkler.

The 28-year-old captioned the post: “He gave me his heart on Valentine’s Day, and I said YES!”

It looks like Gaga is on track for a fairytale wedding, as Tony Bennett has already agreed to sing at the bash.

“They invited me to do it and of course, I will,” he told the New York Post.

Bennett also had high praise for Gaga’s husband-to-be.

“She’s marrying a very wonderful man, very talented and very handsome,” he said. “I think he’s going be highly successful in films.

“He’s a very nice person.”
