Huma Abedin looks effortlessly chic as she attends Jeff Bezos and Lauren Sanchez’s housewarming party in New York City without fiancé Alex Soros

A host of A-listers turned out in their most lavish outfits for Jeff Bezos and Lauren Sanchez’s housewarming party in New York City. Including Huma Abedin, who traded in her fiancé Alex Soros for a night on her own.

Hollywood bigwigs such as Karlie Kloss (31), Nicki Hilton (40) and Jay-Z (54) were also invited to the event at the Amazon CEO’s luxury apartment building in Madison Square Park, where he owns five apartments.

Jeff, 60, has spent a whopping $119 million on apartments. His last big splurge was in 2021, when he bought a $23 million apartment. He was keen to show off his portfolio by hosting the prestigious event, just days after he and his fiancée Lauren returned from a sun-soaked holiday.

And while 47-year-old Huma, Hillary Clinton’s loyal aide, is a seasoned pro at dealing with the city’s elite, she is usually accompanied by her future husband, Alex.

However, the brunette decided to go out alone yesterday, leaving the billionaire heir to party the night away.

She donned a pair of strappy black heels and let her brunette locks fall behind her as she held the hand of her husband Joshua Kushner.

Stacey Bendet, CEO of clothing company Alice + Olivia, also made a stunning appearance in a cheetah print dress.

Fashion designer and model Nicki Hilton followed suit, wearing a snakeskin dress and holding onto the arm of her husband, James Rothschild.

The rest of his real estate portfolio is located in prime locations such as: Lake Washington, Central Park, Texas, Beverly Hills, Washington, DC, Hawaii and Florida.

The star-studded party comes just weeks after he and Lauren enjoyed a lavish vacation on his luxury mega-yacht.

The lovebirds soaked up the sun during their relaxing and romantic vacation in Greece, along with the brunette’s ex-boyfriend Tony Gonzalez, his wife October and a few of their other friends, including Kim Kardashian.

And the future Mrs. Bezos made sure to show off her sexy body during her lavish vacation.

Since early June, Lauren and Jeff have been island hopping on his $500 million luxury mega-yacht Koru, which means “new beginning” in Maori.

Jeff’s 70-metre yacht, which he launched in 2018, currently holds the record for the tallest superyacht in the world.

Fashion model Allie Rizzo and her husband, restaurateur Scott Sartiano, were also in attendance at the star-studded party

The Koru is the second largest sailing ship in the world.

The superyacht holds special significance for the couple: Lauren and Jeff are due to get engaged there in early 2023.

Lauren described the heartwarming moment Jeff got down on one knee during an interview with Vogue last year.

She remembers how Jeff proposed to her on the $500 million superyacht after they enjoyed a romantic dinner under the stars together.

Lauren said Jeff hid the huge diamond ring under her pillow. She said she nearly passed out when she discovered the ring at the end of their romantic evening.

The couple recently moved from Seattle, Washington, to Indian Creek Island in Florida. Jeff purchased three mansions on the island for a total of $237 million.
