Mark Zuckerberg‘s wife Priscila Chan did not hold back when celebrating her 40th birthday this weekend in an extravagant bash that featured a decadent cake and five luxurious outfit changes.

Chan, whose birthday is on February 24, seemed to ring in her new decade early, surrounded by her family and friends who all attended the lavish celebration.

The Facebook founder praised his wife the day after her birthday on Tuesday in a post on Instagram, calling her ‘the most important person’ in his life.

‘Celebrating the most important person in my life. You are a great partner, mother, and friend, and I’m grateful to share this life with you @priscillachan,’ Zuckerberg penned lovingly to his wife.

In his post, he showed off three snaps from the weekend – including a photo of the two of them standing arm-in-arm in front of a gorgeous table setting, which featured long seats, white chairs and big chandeliers hanging from the ceiling.

Chan wore a long, light pink, silky strapless dress with a sweetheart neckline, as she gazed lovingly into Zuckerberg’s eyes.

He also included a clip of the speech he gave at the fete, telling the crowd, ‘Every year, you just grow more vibrant, and more beautiful, and I love you so much.’

On Monday, Chan took to her own Instagram to share photos from the big celebration, which showed four separate snaps in different outfits at various points throughout the evening.

In the first photo, the mom-of-three looked extremely bridal-esque as she wore a square-neck, white gown with a full tulle bottom to blow out the candles on her giant cake.

The dress featured intricate silver beading along the thick straps of the dress and top, and included a blinged-out belt detailing.

The cake, however, might have been even more detailed than her white gown, as it was a giant, pastry model of a silver champagne bucket with a black-and-gold detailed bottle poking out of it.

The champagne bucket, made from cake, included circular, beaded detailing and read, ’40’ on its front, also in silver.

The bottle was equally as personalized, as it read, ‘Priscilla’ on the front in gold cursive, as well as ‘Vintage 1985,’ a play on the year she was born.

Chan blew out the candles as the cake sat on a beautifully-decorated table complete with a sparkling gold table cloth that was covered in tea lights and white roses.

The second photo that the pediatrician shared was a sweet one of her and her husband, Zuckerberg, that was taken from the back.

The black-and-white pic showed them looking at someone appearing to make a speech onstage, as he wrapped his arm around her waist and looked lovingly at Chan.

The silk black slip dress appeared to be the same one made by designer Gabriela Hearst, originally retailing for $3,450.

She wore the dress with a pair of long, black silk gloves.

In the third photo, Chan was seen letting out a huge laugh in the same black dress, this time wearing a taupe-colored, silk shawl and a choker necklace with a gem in the middle.

In the back of the snap, she was surrounded by clapping and cheering friends and family, with many of the men dressed in sharp-looking black tuxedos and bowties.

And, in the last slide, Chan appeared to let loose as she was caught jumping on the dance floor with one arm in the air.

She rocked a skintight, burnt-orange leather dress complete with a halter neck and structured bodice as the philanthropist appeared to dance the night away.

The Massachusetts native wore a coral lipstick on her lips to match the color of her dress.

In the background, her husband, Zuckerberg, also seemed to unleash on the dance floor, as he was seen smiling at his friend, who was mostly cut out of the photo.

It seemed like a great way to ring in her 40th birthday.

‘Turned forty surrounded by family, friends, laughter and dance. I am so so lucky to be so loved,’ Chan penned in the caption of the photo series.

In the comments, she was met with a number of well-wishes, including one from Lauren Sanchez, Jeff Bezos’ fiancée.

The two couples sparked rumors of a rift last month, as Zuckerberg was caught taking a peek at Sánchez’s cleavage during President Donald Trump’s inauguration in Washington.

The Meta founder, who was seated next to Sánchez, couldn’t help but take a quick look at the former Good Day LA host, who wore a plunging white Alexander McQueen pantsuit to the event, complete with a white lace bustier poking out of the one-button blazer.

‘HBD,’ Sánchez wrote to Chan in the comments section, adding two red heart emojis at the end.

On his own Instagram page, Zuckerberg paid tribute to Chan by sharing a sweet photo montage of her throughout the years, as well as pictures of them together.

‘Happy 40th birthday to my beloved Priscilla! Here’s to many more happy years ahead,’ the Meta CEO wrote in the caption.

The couple celebrated their 12th wedding anniversary together in 2024, marking many years together.

They first met in 2003, when they were both undergraduate students at Harvard University, and began dating that same year.

They got married the day after Facebook went public.
