*One of Beyonce’s biggest fans has offered to buy the dress she wore to the Grammy Awards for $250,000.

The singer hit the Staples Center in Los Angeles Sunday night in a white and sheer gown by “Project Runway” designer Michael Costello, and he is currently debating whether or not to let the frock go.

”There’s a guy who’s an obsessive Beyoncé fan who offered us $250,000 for the dress. It’s crazy,” he told People.com. “I’m debating. I want to keep it! It’s a dream come true.”

Michael made six Grammy dresses for the 32-year-old star, and previously admitted he was wowed by her ”tiny, amazing” body. Bey reportedly dropped 70 pounds in recent months after going vegan for 21 days. The artist is now said to be a size 2.

Michael said: ”It was incredible! We didn’t have any of her sizes or measurements. The dress was just made to fit a sample mannequin.

”It’s smaller than a size 4. She is tiny! That dress is at least a 2/4. She looks amazing. I just love the way it all came together. Ty [Beyoncé’s stylist] knew it was going to fit.

”At first I was a little concerned with the pieces I gave. Maybe it needs to be smaller or bigger? When you send something to Beyoncé, you’re just a little concerned, but Ty knew.”
