Their husbands have spent the week travelling to Tokyo and Singapore to play polo - but Meghan Markle and Delfina Blaquier appear to be just as good friends as Prince Harry and Nacho Figueras.
The wives have forged a strong friendship after attending polo matches together to watch their spouses play.
Argentine socialite and businesswoman Delfina, 42, has even previously referred to the Duchess of Sussex, 41, as a 'sister' when gushing over the 'fellow polo-wife' in an Instagram post in 2022.
She also praised the mother-of-two as being 'stronger than she knows' in an interview with Hello! magazine in the same year.
Following a glamorous polo meet in Aspen, Colorado, Delfina said: '[Meghan] is so wonderful and strong. Stronger than she knows. I love being around my friends, and I will always support her.'

In an earlier interview with the publication, Delfina also revealed that the pair referred to themselves as the 'P Wives' which stands for 'Polo Wives'.
Delfina has been married to the millionaire polo player, whose full name is Ignacio Figueras, since 2005 - and the couple attended the royal wedding together in 2018.
Since the Sussexes' move to the US, where Nacho and Harry play polo together at the Santa Barbara Polo & Racquet Club, Meghan and Delfina have become firm friends too.
Last summer Delfina took to her social media account to share an affectionate message about the Duchess of Sussex, saying it had been 'so special' to spend time with her.
Posting a snap of the pair standing while watching their husbands compete at the Santa Barbara Polo & Racquet Club, Delfina wrote: 'M - looking forward to many more of these times with you and H.
'Getting to spend time together over these two months was so special. I wish everyone knew you the way you are.'

In 2022, Delfina posted a gushing post about Meghan on Instagram and said she 'couldn't wait to see her again'
She continued: 'My sister, my now fellow “pwife” (polo wife) -genius of you to come up with this. Can’t wait to see you again soon, to share thrill, hikes, and just more chill time.'
Delfina added: 'You also have my respect. Keep walking, steady and strong. Listen to your heart, that will guide you well, because you have a big one and it’s a beautiful one. I love you my darling.'
Delfina first met her husband Nacho at a polo match in Buenos Aires in 1997. They started dating in early 1998 and welcomed their first son in 2000, and wed in December 2005.
The couple now has four children together: Hilario; Aurora; Artemo; and Alba.
Described by Tatler as 'the David Beckham of Polo', Nacho now holds a 6-goal handicap and an estimated net worth of $30 million and has been modelling for Ralph Lauren since 2000.
He and Harry have been playing alongside each other in charity matches for the past decade, ultimately resulting in them becoming close friends.
Both Prince Harry and Nacho regularly play in Sentebale's charity matches to raise funds for Sentebale, an organisation co-founded by Prince Harry that supports children and young people affected by HIV in southern Africa.
Speaking about his friendship with the royal, Nacho told Town and Country magazine in 2019: 'What I like the most about him is how real he is and how serious he is about improving life for kids that have not had the blessings that we've had.'

Nacho has been to Lesotho with Prince Harry three times, most recently opening the Mamohato Centre together in 2015.
Delfina, who is the daughter of an Argentinian polo player, grew up in Buenos Aires. Until the age of 18, she was an athlete, representing her country at various competitions in high jump.
She went to university and graduated with a degree in landscape design before becoming a professional model and photographer.
While her family spends a lot of time on the road, they are based outside Buenos Aires, where they own a 30-acre ranch housing some 40 world-class polo horses in 38,750-square-foot stables designed by Argentinian architect Juan Ignacio Ramos.
Their family home is just a five-minute walk from the stables.
Writing on her blog, Delfina revealed that her children are homeschooled as a result of their nomadic lifestyle, as the family travels around the world for Nacho's career.
On top of supporting her husband's career and looking after her children, Delfina has a busy creative career. In 2018, she cofounded fashion brand Àcheval Pampa, with the label making its debut at Paris Fashion Week AW18.
The designs are inspired by her Argentinian heritage and achieves elevated gaucho style, an equestrian fashion of South American cowboys.
She also dedicates a lot of time to We Are Figueras, her fashion and lifestyle blog she created to share her family's travels.
On the blog, she writes: 'As the children grow older, I felt I needed to work on something for me, I consider myself a creative type of person and had all this ideas of doing something fun.
'Creating a blog was a lot of fun, and A lot of work. I thought that is was a great idea to put my point of view and share with you things I like doing, seeing, watching, getting or even visiting.
'There is so much out there, and I thought it was a good idea to do it every where I was.'
The polo couple has been friends with Prince Harry for years, and were among the few attending perhaps one of the most exclusive events of the decade: the 2018 wedding of the royal to Meghan.
