Lady Gaga is "desperately trying" to keep her wedding private.

The 38-year-old pop star has been engaged to tech businessman Michael Polansky, 46, for just under a year and they are set to tie the knot at some point but she really wants to keep the whole thing under wraps.

She told E! News: "I'm desperately trying to keep that so private but I would say I can promise that it will be the best day of my life."

The 'Disease' hitmaker had insisted that Michael propose to her with a blade of grass if he ever wanted to get down on one knee and even though he followed through with her wish, she now has the traditional ring.

She said: "He said to me, 'If I ever proposed to you, how do I do that? And I said, 'Just get a blade of grass from the backyard and wrap it around my finger.' And he did. He did that when he proposed.

"It's the blade of grass. It's the green ring that I wear."

Despite wanting to keep the whole thing to herself, the 'Bad Romance' singer previously joked that she could see herself opting for a simple day but it could just as easily turn into a "circus" of a wedding.

Speaking on 'Jimmy Kimmel, Live', she said: "We actually talk about going to the courthouse, just the two of us, and ordering Chinese food.

"Knowing me, also, it could become like a circus with unicorns."

Gaga - whose real name is Stefani Joanne Angelina Germanotta - has also explained that her significant other was able to see her for who she really is "outside" of her stage persona.

She told Vogue: "It was really kind of special.

"I met this totally supportive, loving human being who wanted to get to know me--outside of Lady Gaga!"
