Famous Wedding Singers Who Have Serenaded Couples At Their Nuptials

Katy Perry's own marriage ended in divorce, but that didn't stop the "California Gurl" from belting out her chart-topping tunes at Australian actress Holly Valance's wedding to billionaire real estate mogul Nick Candy last weekend.

Perry was reportedly paid $1.9 million to play a 45-minute set at the wedding on September 29. The newlyweds are former neighbors of Perry's, and her performance accounted for nearly half of the wedding's reported $4.7 million total cost.

But Perry isn't the first -- and certainly won't be the last -- celebrity wedding singer. Click through the slideshow below to see 11 others.
