Report: Prince Harry has "changed considerably" since marrying Meghan Markle

It seems that Prince Harry is a changed man.

As reports of brewing tension within the royal family continue to command headlines, another recent exposition reveals the impact that Duchess Meghan has had on Prince Harry as early as 8 months after their nuptials.

Close friend of the royal family (and former friend of Princess Diana) Lady Colin Campbell revealed during the news documentary "Kate V Meghan: Princesses At War," the Duke of Sussex is completely "beguiled" by Meghan.

Lady Campbell, who is the author of three books on the royal family, said:

"Everything I hear is that Harry is completely beguiled by Meghan and completely enthralled to her and has changed considerably." She also detailed the impact that the mom-to-be has had on the royal, including exercising more and cutting smoking and alcohol from his diet.

Not bad, Meg.

But it's also been suggested over the past few that she might be the cause of a rift between Harry and his brother. Rumors began circling that when the Sussex family announced they were moving out of Kensington Palace -- where Prince William and Duchess Kate reside with their three children -- to Windsor Castle's Frogmore Castle, that the brewing tensions between the "Fab Four" might have something to do with it.

Continued royal biographer Katie Nicholl to the Daily Mail, "William was quite concerned that the relationship had moved so quickly and being close to Harry, probably the only person close enough to say to Harry 'this seems to be moving quickly, are you sure?'"

"Harry is hugely protective of Meghan, he saw that as criticism, he interpreted that as his brother not really being behind this marriage and I don't think things have been quite right ever since," she continued.

However, other insiders squashed claims that Meghan was causing trouble, and that it wasn't the reason behind Prince Harry and Meghan's move.

"People are genuinely pleased to see them so happy," explained reporter Rebecca English. "The truth is that there simply isn't enough room at Kensington Palace for them and I know they have been looking at Windsor as a possibility since before the wedding."
