'She stopped reading things after finding out about her sister's book,' a friend told DailyMail.com. 'She cried when she found out about it.
'Out of everything that's been said, the one thing that really upset her was that [the book]. She and Samantha never had a very good relationship and she feels her sister is using her position for profit.'
Meanwhile friends of the former Suits actress told People magazine that reports about Meghan being difficult were blatant "lies and untruths" spread across the media.
The friends - who chose to remain anonymous - include Meghan's "longtime friend, a former costar, a friend from LA, a onetime colleague, and a close confidante”.
“We worry about what this is doing to her and the baby,” said Meghan's former co-star, “It’s wrong to put anyone under this level of emotional trauma, let alone when they’re pregnant.
“We want to stand up against the global bullying we are seeing and speak the truth about who our friend, a mother-to-be, really is.”
