The final preparations are underway for Microsoft heiress Jennifer Gates' spectacular wedding to Egyptian equestrian Nayel Nassar in a lavish ceremony in Westchester, New York.
At Friday night's rehearsal dinner, father of the bride Bill Gates and his 25-year-old daughter could be seen sitting on the outdoor deck of her Westchester mansion with the pair laughing and joking before appearing deep in thought.
Bill and Melinda Gates, who divorced in August after 27 years of marriage, were seen together mingling with guests at the rehearsal dinner.
The outdoor wedding is set to be held on Saturday afternoon in an elaborate tent city erected on the family's 142-acre estate in North Salem, New York.

On Saturday morning, workers were scrambling to make last second adjustments with the wedding just hours away. This included a debate over climate control.
'I'm not sure what temperature to leave the venue so the dance floor doesn't bubble, and so we don't kill the trees,' one crew member warned.
As if on cue, one of the newly-erected trees toppled over onto the dance floor.
'It's a bloody mess down here,' one staffer laughed.
'I'm on it,' another replied.
Workers were hauling in white flowers in orange Home Depot 5-gallon buckets, to be placed along a walkway leading into the ceremony.

The workers brought in their own catering, boxes of Dunkin Donuts and gallons of coffee.
Five ladies who call themselves 'the Sisterhood of the Walking Pants' strolled by the event, where a loud bandsaw hurt their eardrums.
'Here it's hours before the wedding and so much still to be done,' Diane, 80, told DailyMail.com. 'If I was the mother of the bride, I'd have so much angst.'
They were cracking jokes about crashing the party.
Amy, 62, took out a necklace of cultured pearls and placed it over her Hard Rock Cafe t-shirt. She was on crutches.
'She came out of rehab for this,' quipped her friend Joan, 56.
