"The DUCHA** should be humane to our father who has given her everything and this media crap can stop!" This gesture was just one way that Meghan has tried to keep up with the few remaining friends she has left.
"People need to stop being so blinded by glare of celebrity status and wealth", she wrote, as quoted by the Evening". She's wearing the kind of clothes that the other women simply wouldn't dare wear, including boatneck silhouettes, a sleeveless trench dress and even bold denim dresses.
"I see it in her eyes, I see it in her face and I see it in her smile". I think she's under too much pressure.
While Meghan remains close to her mum Doria Ragland, who recently moved to the United Kingdom to be closer to her daughter, she's very publicly estranged from others.
The childhood friends had a falling out after Priddy, who was Meghan's maid of honor at her first wedding, disapproved of how she broke things off with her film producer husband Trevor Engelson.
"I tried to get details from her, but she wouldn't tell me".
