I do feel a bit sorry for them. It was not his or her fault that they were born into millions/billions and into a major spotlight. At least they may be able to relate to eachother on that score.
Imagine starting out at something and having millions of people take the piss. If your dad’s mate helps you onto an electrical apprenticeship or whatever, nobody shouts nepotism or says oh aren’t you shit at electrics (yes because you just started). Gordon Ramsay is literally his dad’s mate and helped him with cheffing.
That said, a lavish vow renewal ceremony after 2/3 years does seem odd. It makes me wonder whether they have nothing to do/are bored, or overly hung up about things that weren’t perfect on the original wedding day (which you just really have to forget about).
Sad that he’s fallen out with his parents. Whatever faults they have, they ultimately love him very much - that is evident from the photos over the years.
