Prior to the pair's nuptials, caterers and employees were seen preparing for a big celebration in the backyard of Spiegel's home.

According to sources, it was a private small ceremony for family and friends -- around 40 guests total -- and everyone was chauffeured to Spiegel's house in cars.

Women were seen wearing colourful floor-length dresses and the men wore suits.
