Australian singer/actress Holly Valance married her billionaire fiance in a lavish ceremony in California on Saturday.

The former Neighbours star exchanged vows with Nick Candy in Beverly Hills in an outdoor ceremony in front of famous guests including music mogul Simon Cowell, as well as friends and family from across the world.

The 29-year-old bride donned an extravagant white dress and long veil, and carried a red bouquet.

The wedding ceremony came after the couple reportedly held a rehearsal dinner in Malibu on Friday night, and they are said to have put together an informal post-wedding barbecue for guests on Sunday.

Candy proposed to Valance in December during a vacation in the Maldives.
