Getting on with your partner's circle of friends can be a make or break situation in any relationship.
And it looks like the Duke and Duchess of Sussex are not exempt from this age-old conundrum.
In fact, an explosive new report published by British newspaper The Express claims Prince Harry is freezing out some of his more raucous party pals from his single days.
According to an insider, Harry's close mate from his Etonian school days Tom Inskip has been given the cold shoulder of late.
"Like several others who were considered a questionable influence on Harry during his bad old bachelor days, Tom has been dropped, even though he himself now has a lovely wife, Lara," a spy told the publication.
Banker Tom, also known as Skippy, has long been Harry's wingman and was with the prince during his infamous strip billiards scandal in Las Vegas in 2012.

Tom was also by Harry's side in 2011 when the royal was snapped jumping into a nightclub pool in Croatia.
Last March, Prince Harry served as one of Tom's ushers at his wedding in Jamaica and brought along Meghan in what was one of their first public outings as a couple.
But since Harry wed Meghan in May, his friendship circle has reportedly been given an overhaul.
Another pal reportedly on the chopping block is PR exec and London socialite Astrid Harbord.
"It's all part of Meghan's quiet airbrushing out of Harry's old posse. She doesn't want temptation - of any sort - being put in his way while they concentrate on starting a family," the insider revealed.
Astrid, who is friends with Princess Eugenie, Princess Beatrice and the Duchess of Cambridge, was one of Harry's party pals and was previously linked to him in 2009 after she was seen heading back to Clarence House with the prince at 3am after a wild night out.
So, just who are Harry and Meghan hanging out with?
According to The Mail on Sunday, the royal couple are enjoying the quiet country life at their secluded "safe haven" house in Oxfordshire's Great Tew Estate.
Much of their time here is spent with their new besites, George and Amal Clooney, with the foursome said to head out on long countryside walks together.
Other friends who have been invited to stay include Meghan's stylist and close friend Jessica Mulroney, tennis star Serena Williams and her husband, Reddit founder Alexis Ohanian, actress Priyanka Chopra, fashion designer Misha Nonoo and royal bride to-be Princess Eugenie and her fiance Jack Brooksbank.
"Harry and Meghan have spent much of their summer at the house. It's their safe haven and the reason they decided to get another dog as they love walking around the grounds," a source explained to the Mail on Sunday.
These latest claims of Harry freezing out his friends comes off the back of claims his social circle aren't too fond of Meghan due to her progressive political views.
"Her politics are an issue. She is ultra-liberal and that trendy-lefty stuff does not go down well with some of Harry's friends," Lady Colin Campbell, a former confidant of Princess Diana, recently alleged to The Daily Beast.
