Meghan Markle blasted by half-brother who claims she is 'trying to reinvent herself as the new Princess Diana'

Meghan Markle's half-brother has blasted the Royal bride-to-be and claimed she is "acting phoney" and "trying to reinvent herself as the new Princess Diana."

Thomas Markle Jr's angry remarks come after fellow half-sibiling Samantha Grant demanded Prince Harry "man up" and "stop letting his fiancee ignore her family".

She had previously attacked her half-sister for "inviting 2,000 complete strangers" to the May 19 Royal Wedding at Windsor Castle and "ignoring her family."

Now Thomas Jr, 51, has spoken out, telling the Daily Mirror his estranged half-sister has "turned into a different person" and "is acting phoney".

Ms Markle and Prince Harry were carrying out their first major engagements together at the Commonwealth Youth Forum on Wednesday. They were set to attend a Commonwealth Women's Empowerment event hosted by Boris Johnson on Thursday.

He said: "Meg likes to portray herself as a humanitarian, a people's person and a charitable person but she is none of those things to her family.

"She is giving the greatest performance of her life. She is acting phoney. Once she got into Hollywood she turned into a different person. She's clearly forgotten her roots and her family.

"There's a whole different side of her that has started to surface and it's ugly to see.

"I've read that Meg wants to be like Diana. Diana was worshipped by everyone in the world. She was loved for the right reasons."

He added that Ms Markle was "not genuine" like Diana.

Thomas Jr claims he and Ms Markle spent every other weekend together between 2009 and 2011, caring for their Dementia-stricken grandmother Doris.

He now claims to have contacted Buckingham Palace three times in a bid to re-establish contact with Meghan with no response.

On Wednesday, half-sister Samantha unleashed another furious rant at the Royal couple as they attended their first Commonwealth event together in London.

She accused Prince Harry of contradicting himself for “shouting about” humanitarianism but “allowing Meg to ignore the Markles” in an angry tweet.

Prince Harry and his fiancee are set to invite an additional 1200 members of the public to celebrate their wedding in the grounds of Windsor Castle on May 19.
