Natalie Maines has a very special wedding gift for Howard Stern. The shock jock announced on his SIRIUS radio show Monday that the Dixie Chicks singer has agreed to sing at his upcoming wedding to model Beth Ostrovsky.

Stern and Ostrovsky have reportedly become close friends with Maines and her husband, 'Heroes' actor Adrian Pasdar. In late 2006, Stern was on vacation in Mexico when he ran into the couple. He told his radio audience that he and Pasdar bonded over chess games.

Stern has also revealed that pop/jjazz vocalist Phoebe Snow and Train lead vocalist Pat Monaghan will be performing at the ceremony. No word yet on when the nuptials will take place, or what Maines will sing.
