Taylor Kinney and Lady Gaga

The pop star - who has been with Taylor Kinney since September 2011 - is reportedly keen on a design by the Italian, and asked her to create a black and gold silk gown with diamonds in the bodice.

A source told The Sun newspaper: "Gaga's spending millions on her wedding to Taylor Kinney and Doatella Versace's designing a typically over-the-top dress which on its own will cost thousands.

"She thinks white is cheesy and wants black and gold silk with all these crazy removable bits."

The extra "bits" include a removable skirt and train, which would then be converted into a separate gown for the ceremony.

'The Edge of Glory' hitmaker and the 'Vampire Diaries' actor have had trouble finding time for the wedding among the singer's heavy schedule but a break from recording and touring should allow a date to be set for the summer.

It's also reported they want to get married in New York to allow her grandmother Angelina Germanotta to attend.
