Kelly Clarkson is calling out an establishment’s big mistake. Big. Huge.  

The Grammy winner shared she had an unsatisfactory experience while shopping in a swanky New York City store, comparing the encounter to how Julia Roberts’ character Vivian was treated in the 1990 film Pretty Woman.

“Just drove all the way to Brooklyn to check out this store I thought looked really rad and had a few things in mind to buy,” Clarkson wrote on X Oct. 10, “and literally was looked at as if I couldn’t afford it and was told he could find something comparable for me.”

“Wow, dude,” she added. “You’re an idiot and just lost a huge sale.”

The “Stronger” singer went on to name drop the store before telling her followers to visit the establishment “if you enjoy being treated like Julia Roberts’ character in Pretty Woman,” adding alongside a thumbs down emoji, “For sure, check it out.”

E! News has reached out to the store for comment but has not heard back.
