Fashion faux pas?

Supermodel Lily Chee, 21, came under fire this weekend after she wore a surprisingly low-cut dress to the Monaco Grand Prix.

She displayed the dress on her Instagram Story before the race on May 25. The outfit was quite revealing, showing part of her backside.

“Why is her ass crack out?” one person asked after sharing a screenshot of the controversial picture to social media.

One commenter compared it to an ill-fitting plumber’s crack rather than a glamorous look. They mentioned that she needed better friends.

“I cannot get behind the exposed crack trend,” a third critic wrote. “It is not the new cleavage, pull your pants up.”

Some people, on the other hand, were more supportive of the socialite and her daring choice of attire in Monte Carlo. They came to her defense despite the criticism.

“She is there as a TAG Heuer guest, just like Cindy Mello and others,” a fan of the 21-year-old influencer pointed out. “Lily is posted on the TH IG stories.”

“BECAUSE IT’S ART,” wrote another supporter.

Chee was not the only celeb in attendance, turning heads and raising eyebrows at the annual F1 race in Monaco on Sunday.

A slew of A-listers were also there, including Jeff Bezos and his fiancée Lauren Sánchez; actress Sofía Vergara; Grammy-winning singer Dua Lipa; and British supermodel Naomi Campbell.

Chee first made headlines in 2014 when, at the age of 11, she made $22K modeling for brands like Nike, Levi’s and Ralph Lauren.

“Max was a little skeptical at first, but Lily was super keen to pursue it,” her mom, Rebecca Chee, said at the time. “We went to a go-see [audition] for Nike and got an immediate callback.”

“You don’t put your children into modeling because of the money,” her mom continued. “Modeling is not the be-all and end-all, and we make sure she has lots of other interests and options.”

Ten years later, Chee made headlines once again after she was rumored to be dating Hollywood hotshot Toby Maguire, 49.

The pair was spotted leaving billionaire Michael Rubin’s white party together on July 4, 2024, although the “Spider-Man” star’s ex-wife, Jennifer Meyer, quickly dispelled the Maguire-Chee romance rumors.

“He was kindly helping a friend to her car,” Meyer, 48, claimed at the time. “And now he has [been] blasted online for dating someone he is not.”
