With one Instagram post, Miley Cyrus has seriously ticked off Dolce & Gabbana.

Miley Cyrus has drawn the ire of luxury Italian fashion house Dolce & Gabanna after publicly criticising their political views.

The singer’s musician brother, Braison, walked in the luxury label’s Spring 2018 show at Milan Fashion Week over the weekend.

While Cyrus used Instagram to praise her sibling for “trying something new” she was also quick to take aim at the brand.

“I love you Prince Suga Bear and seriously congratulations on your experience! I am so proud of you always,” the 24-year-old wrote.

“PS D&G, I STRONGLY disagree with your politics…. but I do support your company’s effort to celebrate young artists & give them the platform to shine their light for all to see!”

It's believed the singer's comment was in reference to Dolce & Gabbana's support of Melania Trump.

The US First Lady is a long time customer of the label, and was earlier this year praised on social media by its co-founder Stefano Gabbana, who referred to her as a "DG woman".

Yet regardless of the motive behind Cyrus's statement, Gabbana wasn't impressed.

"For your stupid comment we never more work with him," the designer commented on another of her Instagram posts.

And he didn't stop there.

"We are Italian and we don't care about politics and mostly neither about the American one! We make dresses and if you think about doing politics with a post it's simply ignorant," the 54-year-old wrote on his own Instagram account.

"We don't need your posts or comments so next time please ignore us!!" [sic]
