Mark Zuckerberg and his wife Priscilla Chan put their own spin on 'mob wife' trend as they attend UFC 300 - after Jeff Bezos's fiancee Lauren Sanchez went viral for her take on the look

Imitation is the most sincere form of flattery - and if the critics are correct, Mark Zuckerberg and Priscilla Chan's latest 'mob chic' fashion adventure is the ultimate homage to Jeff Bezos and Lauren Sanchez. 

The Meta CEO and his wife debuted a different look at Saturday's UFC 300 event, showing off a more daring fashion choice.

'What an epic night,' the tech billionaire gushed in a Facebook post on Sunday, alongside several pictures and videos of the event.

He then congratulated the event's winners, tagging Aljamain Sterling, Bo Nickal, Weili Zhang, Max Holloway and Alex Pereira in the post.

The comparison between the billionaire couples was first made by Business Insider, who suggested the couple were coming for Bezos and Sanchez's 'mob chic crown.'

While this isn't the first time Zuckerberg and his wife have been seen at a UFC event, the couple's major fashion glow up had other fans talking. 

Zuckerberg, 39, donned a white shirt, gold chain and black pants to watch the fight, and pose in photos with UFC champions.

His wife opted for an all-black outfit, wearing a short black dress with tights and black leather shoes, with a solid gold necklace.

She walked in wearing black sunglasses to accompany her sleek look.

However, Facebook users were split over the tech founder's new look, with one person joking: 'One thing about Zuck — he is going to dress like he got no money.' 

'First time I’ve ever seen Zuckerberg wear jewellery.. is he trying to be cool or something,' questioned another person.

Others applauded his new look. 

'I like your outfit mark,' an enthusiastic fan wrote. 'Still rockin those plains but a different style. Keep it up mark! Ill be waitin for your next post.'

The Facebook founder, who trains in mixed martial arts himself, was even challenged to a fight by fellow billionaire Elon Musk last year.

Zuckerberg has been fully engrossed in MMA training, with the billionaire tearing his ACL in November while training.

He has been eyeing a return to the cage in September after revealing recovery was 'going well' post-surgery, but he has been unable to stay away from the sport in his competitive absence.

Zuckerberg shocked fans by appearing in the corner of Alexander Volkanovski in California in February, where he walked to the Octagon with the Australian featherweight and his team ahead of his bout against Ilia Topuria. 

However, he could only watch on as Volkanovski suffered a knockout defeat to Topuria on the night.

It's not the first time a billionaire couple has gone for a darker fashion choice. 

In January, Lauren Sánchez was spotted wearing a daring 'mob wife' inspired look at Milan Fashion Week.

The former journalist, 54, donned a low-cut, floor-length sheer dress with lace detail, catching the eye of fashion lovers, who declared she had fully adopted the aesthetic. 

In addition to her figure-hugging black dress, she also wore a striking black jacket over her shoulders and her long hair flowing with choppy bangs. 

While the billionaire and his wife may be just experimenting with his fashion; the parallel to Bezo and Sanchez did not go unnoticed.

The trendy aesthetic is inspired by wives in famous mob movies, such as Carmela Soprano and Adriana La Cerva from The Sopranos, Karen Hill in Goodfellas, and Elvira Hancock in Scarface.

The outfits are usually loud and flashy, with big fur coats and busy prints being key components to achieving the looks.

This is paired with black clothes, gold bling, sunglasses, striking makeup and 'big' blown-out hair - often including a smokey eye look as well red lipstick and bright nails, such as red or French tips.

Celebrities such as Dua Lipa, Taylor Swift, and Jennifer Lawrence, have all adopted the mob-wife look - and recently snapped in garish designs and floor-length fur coats.

Dua, 28, was recently seen in New York in a black lace ensemble and fur coat.

Jennifer Lawrence, 33, has also entered her mob wife phase, with The Hunger Games actress snapped leaving the Golden Globes afterparty in a showy velour look.

During a ski trip in Aspen, Kendall Jenner, 28, looked mob-wife chic in a floor-length fur coat paired with heeled black leather boots and matching leather gloves.
