No one throws shade quite as well as Queen Elizabeth. People on social media sure seem to think so, after spotting a key detail in her outfit last night.
While First Lady Melania Trump is no stranger to making headlines for her sartorial choices, another head of state stole the spotlight during her first official trip to the United Kingdom with President Trump - and it's none other than Queen Elizabeth II.
The Queen attended the prestigious dinner in a cream dream and royal blue sash - but it was another part of her outfit that spurred headlines. However, the website of the royal family does not list any such rule.
"The number of stones represent the number of diseases that the Burmese people believe can afflict the human body", the explanation reads.
The Queen was very honest as she welcomed Donald Trump to the UK.
The rubies in the tiara are meant to protect against evil and illness. She commissioned the tiara in 1973 to include 96 rubies that were given to her by Burma as a wedding gift.
"'I totally understand why people want the queen to be trolling Trump, '" Ruiz quoted Morgan as saying.

The stock market's tumble on Friday all but guarantees that May will be the first monthly loss for the market in 2019. No formal talks are now scheduled between the U.S. and China after the collapse of discussions in early May.
Fellow Twitter user @agrippamom added "She's so wise".
According to the Evening Standard, traditional protocol dictates that in order to touch the Queen, she must first offer her hand to you.
The symbolic meaning of the tiara calls into question the Queen's decision to wear it on the evening when she must entertain Donald Trump. Twitter users were quick to praise the queen for this subtle disrespect.
Another joked: "Queen Elizabeth throwing some shade?!"
It's not the first time people on the internet have speculated that the 93-year-old has silently mocked the U.S. leader. Former first lady Michelle Obama also created controversy when she "laid a hand across her shoulder" in 2009.
So, is Her Majesty a high-class troller, or was the whole thing just a big coincidence?
The Palace are yet to comment on the intense social media storm that has ensued, and it's likely they never will, considering it is based on sheer speculation.
