Meghan Markle's half-sister believes a "jealous streak" in the mum-to-be may be the reason behind her reported fall-out with sister-in-law the Duchess of Cambridge.

While most of the rumours about the reported royal rift have started to die down, Samantha Markle has now shared her thoughts on what happened.

She claims Meghan "likes to be the centre of attention", but hopes she will be able to reach out to her sister-in-law when the royal baby arrives.

Speaking on QuestRed's documentary Meghan and Harry: A Royal Baby Story, she said: "I believe that there is a jealous streak in Meg.

There have been rumours of a rift between Kate and Meghan

"She does like to be the centre of attention, I feel that's part of what's going on now."

She also spoke about her hopes for Meghan and Kate's relationship after the baby is born.

She said: "I would hope that Meghan would take some pointers from Kate, who is quite experienced now, and can probably guide her in ways how to help shelter the kids while at the same time educating them and giving them a realistic sense in who they are in this busy world."

While many people believe Meghan and Harry will shun the tradition of a 'royal nanny', Samantha believes they will have some help.

She believes Meghan will have lots of help

She says: "I think Meg will definitely get a nanny. I'm pretty sure that her threshold for stress could be quite low in the beginning.

"How many rooms in Frogmore? I can see them all being filled up with nannies.

"Meghan is very strong-minded and there will probably definitely  be a butting of heads but Meghan could learn and grow from that.

"So if the nanny is strong enough then she won't leave in tears."

Samantha also shared her views on her sister's birth, saying: "Hopefully she'll have the birth in whatever comfortable safe setting she feels best in, because it's a difficult thing and she has to be comfortable."

During the interview Samantha, who shared Meghan's dad Thomas Markle, expressed her sadness at the family fallout.

She said: "We're a pretty normal family who have all shared in your life experiences.

"It's not that we weren't ever there, we've gone to your dance recitals, holidays, Thanks Giving, being on the phone giggling and laughing.

Meghan's new life is very, very different

"Now, all of a sudden we don't exist. You can't hurt people like this then turn around and flip the script and play victim.

"It's important that children have a bigger sense of their family and where they come from.

"I would like to think that this child would have access to the best parts of grandad, as we did when we were kids.

"I would hope that  grandchild would get to know that side of the Markles.
