Midler to sing at Kidman's wedding

Bette Midler will perform at Nicole Kidman and Keith Urban's wedding next month, singing her hit Wind Beneath My Wings.

Kidman begged Midler to take to the stage, because the track is her all-time favourite, according to reports.

A source tells British newspaper The Sun: "It is Nicole and Keith's special song. Bette and Nicole are very close. They were both born in Hawaii, so they have a lot in common."

The couple are due to marry in Sydney, Australia on June 25.
