Colin Cowie's Fantasy Weddings

When fitness expert Bob Greene got engaged to the love of his life, Urania, Oprah knew she wanted to throw them a wedding. "As you all who watch the show know, I call Bob my brother," she says.

Set on Oprah's California estate, Oprah and Colin worked as a team from day one to create an unforgettable event. Every detail was discussed—from coral roses dangling from the trees to violins serenading the happy couple. "Nobody in the world throws a party like Colin Cowie," Oprah says.

And guess who was the best woman? That's right! For Bob, Oprah walked down the aisle in a white dress.
