Some of Meghan Markle's guests broke protocol at a gathering before the royal wedding reception by filming their experience and posting the videos to social media.
The 600 guests who attended the exclusive Frogmore House party hosted by Prince Charles were given a seven-page etiquette booklet before the wedding, and among the instructions were strict rules against the use of mobile phones, Daily Mail reported.
But some high profile friends of the Duchess of Sussex ignored the rules by posting photos and videos of their royal wedding experiences to social media.

Rachel Renna, the makep artist for Markle's best friend Jessica Mulroney, posted a short Instagram clip showing Ms Mulroney mingling with guests at the party, which followed the wedding ceremony at St George's Chapel and an afternoon reception at St George's Hall.
Ms Renna boasts some 10,000 Instagram followers. The video has since been removed.
Ms Mulroney is the wife of Ben Mulroney, the son of former Canadian Prime Minister Brian Mulroney. The BBC describes Mr Mulroney as "Canada's answer to Ryan Seacrest"; his wife, Jessica, is fashion advisor to Sophie Gregoire-Trudeau, the current Canadian Prime Minister's wife.
Ms Markle, born 1981 in California, starred as Rachel Zane in the television series Suits from 2011 to 2017, which was filmed in Toronto, Canada.
Ms Renna wasn't the only celebrity to break protocol at the wedding reception. Tennis superstar Serena Williams and actress Priyanka Chopra also posted photos and videos of themselves to Instagram between the wedding festivities, despite instructions to "surrender" their mobile phones.
