The Duke and Duchess of Sussex have already arrived in Sydney for their Australian royal tour.
And soon they will be welcoming Markle's best friend Mulroney and her husband Ben Mulroney, after he confirmed they'll be joining the couple.
He shared the news last week on his Insta Story and it is believed they're here on an "unofficial" capacity.
This isn't Mulroney's first Invictus Games. She famously joined Markle for the Toronto Games- a multi-sport event for injured and wounded military veterans.
The Duke and Duchess of Sussex's first official overseas tour kicks off in Sydney, and the pair will attend the opening ceremony of Invictus Games on Oct. 19.
The ladies have been friends since 2011, and are said to have bonded over a shared love of yoga. They even travelled to Italy together back in 2016.
