She shut down her social media accounts in January 2018, just months after announcing her engagement to Prince Harry.
But new sources are now claiming that Meghan Markle, 37, had a 'secret' Instagram account which she used to follow her friends until just a few months ago, when she shut it down after seeing vile comments from trolls.
According to the reports, the Duchess of Sussex, who is expecting her first child with Prince Harry in April, was left feeling 'isolated and alone' by the cruel taunts, and closed the account just before Christmas to 'protect her mental health'.
Speaking to The Sun about Meghan's reaction to negative headlines, an insider admitted they left her feeling upset.
They revealed: 'Since she shut down her public Instagram, she'd had a fake account to follow her friends. There was some really vile stuff written by social media trolls and obviously she also saw the headlines about her.
'It really got to her and, in the end, she had to shut down that account just before Christmas, too, to protect her mental health. She felt very isolated and alone.'
They added of the pregnant duchess: 'She doesn't feel safe enough to go out on her own without protection.'
The majority of royal family members do not have social media accounts, with the exception of Princesses Beatrice and Eugenie.
