Duchess Catherine and Duchess Meghan are "closer than ever"

A source told 'Entertainment Tonight': "The sisters-in-law are closer than ever."

Catherine, 36, does a lot of charity work for mental health organisations and sports alongside William and Harry and now Meghan - who was known by her maiden name Markle before she married the flame-haired prince - is keep to follow suit.

An insider explained: "Meghan is set to announce her first patronage imminently."

But while Meghan is happy to throw herself into her new royal duties, her father Thomas Markle - who was unable to attend the wedding because he had to undergo surgery on his heart in the US - is convinced she's really unhappy and stressed.

The retired lighting director - who hasn't seen Meghan since before she got married - said recently: "My thing about my daughter right now is that I think she is terrified. I see it in her eyes, I see it in her face and I see it in her smile. I've seen her smile for years. I know her smile. I don't like the one I'm seeing now. This one isn't even a stage smile - this is a pained smile. That might be just having a couple of bad days. I don't know. It really worries me. I think she's under too much pressure."

Thomas has regularly accused Meghan of trying to "freeze him out" of her life.

He explained: "If I chose in a month, or couple of months, to go to En¬g¬land -- I want to see my daughter. I'm thinking about it. I don't care whether she is p***** off at me or not. I'm not going to wave flags and make a fool of my¬self."
