Jennifer Gates leaves New York City before heading upstate for her extravagant ...

Jennifer Gates is preparing for her big day with some beauty treatments and pampering in New York City as the countdown to her extravagant wedding approaches its final hours.

The bride-to-be was seen leaving the ritzy Greenwich Hotel in downtown Manhattan Thursday morning before heading off for some bridal treatments at a salon in Tribeca. 

Jennifer, who will tie the knot with millionaire equestrian Nayel Nassar, 30, on Saturday, looked elegant in a cream-colored duster coat, white turtleneck, jeans, and a chain-strap purse.  

Exclusive DailyMail.com photos show the 25-year-old stepping out in a black face mask before getting into a black SUV. She was assisted by her chauffer in loading her designer baggage into the trunk.

A hotel porter was also seen packing a second vehicle with several garment bags, including one that may have been carrying the bride's wedding gown. 

Jennifer met up with mom Melinda and some friends at Salon M in Tribeca where they spent a few hours getting dolled up. She later parted with ways with her mother and returned to her hotel Thursday afternoon. 

The eldest daughter of billionaires Bill and Melinda Gates has had a busy few days in Manhattan preparing for her nuptials which will take place on Saturday at her 124-acre, $16million North Salem farm that her parents purchased for her in 2018 shortly after her graduation from Stanford University.

Aerial photos of the property have offered a glimpse into the scale of the lavish wedding celebration that is rumored to cost $2million. 

On Wednesday Jennifer was spotted stepping out in New York City for some quality time with her mom. 

Exclusive DailyMail.com photos show the mother-daughter duo all dolled up as they entered Manhattan's iconic Plaza Hotel.  

Jennifer wore an all white lace gown and her ginger locks were down and curled, while her mother wore a pink dress with a matching wrap and heels. 

On Tuesday night, DailyMail.com spotted the bride and groom getting out of black SUVs before checking into the luxury Greenwich Hotel in Manhattan, where rooms range from $850 to $2,500 per night. 

Jennifer, the eldest daughter of billionaires Bill and Melinda Gates, and her millionaire equestrian fiancé Nayel Nassar, 30, were accompanied by a heavy security detail, consisting of seven guards and four vehicles. 

Nayel appeared in high spirits as he was seen laughing with security. 

Before getting all dolled up with her mother on Wednesday, Jennifer was seen grabbing coffee in Manhattan with an unidentified blond friend. 

She strolled the city streets before heading into Sania's Brow Bar, where she stayed for about 20 minutes and then returned to her hotel. 

Exclusive DailyMail.com photos previously showed tents being erected at Jennifer's 124-acre, $16million horse farm in North Salem, New York, that her parents bought her in 2018 after she graduated from Stanford University.

Acquaintances of the 25-year-old champion equestrian tell DailyMail.com that 'everything is being tastefully done, even the port-a-potties are beautifully designed' for her wedding to fellow rider Nayel on Saturday. 

However, not everyone is pleased at the arrangements. 

'It's totally over-the-top. Just incredible extravagance and unpleasant for the neighbors and the wildlife that made their home on the farm,' an insider said. 

'Trucks are constantly coming and going into a field on the farm where deer used to graze. There's a noisy forklift and dozens of workers are driving around on ATVs.' 

One neighbor told DailyMail.com that the ceremony will be held at the farm.  

'Jenn's hoping the actual ceremony can be outdoors but in case the weather is bad, they've put up huge tents in one of the fields and they're also rushing to build several state-of-the art, temporary steel-and-glass pavilions,' they said. 

And with billionaire parents, the most wealthy and high-profile guests are expected to attend.
