How Duchess of Sussex Meghan Markle will be spending her first royal birthday this weekend

Meghan Markle turning 37 years old on Saturday, August 4 will mark her first birthday as the Duchess of Sussex.

There won't be any lavish parties thrown for the former Suits star this weekend, however - she'll instead be accompanying husband Prince Harry to his childhood friend's wedding.

Royal photographer Tim Rooke confirmed on Twitter that Harry would be the best man at his friend Charlie Van Straubenzee's wedding on August 4 - the same day a Meghan's birthday.

Charlie was reportedly one of the ushers at Meghan and Harry's royal wedding earlier this year. He will be marrying Daisy Jenks in Churt Surrey.

Meghan's birthday celebrations look set to be a far cry from last year, when Harry whisked her away for a romantic safari getaway in Africa.

August 4 is also a significant date for Meghan's grandmother-in-law, Queen Elizabeth, as it happens to be the birth date of the late Queen mother.
