'Meghan & Harry: A Royal Baby Story' Sneak Peek: Why Meghan Markle Was Dubbed 'Difficult Duchess' (Exclusive)

ET has an exclusive clip of TLC's upcoming documentary about Meghan Markle and Prince Harry's love story and baby on the way.

Meghan Markle has been dubbed the "difficult Duchess" by British media, but is she?

Royal experts investigate the Duchess of Sussex's high staff turnover, as well as her and Prince Harry's baby on the way, in Meghan & Harry: A Royal Baby Story, airing April 9 on TLC.

"There have been a lot of rumors about Meghan and what she's really like behind the scenes," royal expert Katie Nicholl says in ET's exclusive clip of the special. "Of course she's an actress, and when you see her in public, that mega smile, she is the consummate professional. And this reputation for being 'difficult' was linked to an unusually high turnover of staff at the palace."

Another expert explains how she gets up in the morning extra early to get her day started and texts her team members what her plans are, which was something different for the staff and their protocol. Back in December, a source told ET that the Duchess "raised eyebrows" among staff for her "rather direct approach" to life in the royal spotlight, a method that doesn't necessarily "sit well" with the "more refined British."

While she has "ruffled some feathers" for her proactive behavior and been given the titled "difficult Duchess" by tabloids, broadcaster Sarah-Jane Crawford says in the clip that she doesn't think it's fair.  

"There's nothing wrong with being a woman who knows what she wants," Crawford explains. "The fact that she is a feminist, she is somebody who is known for really speaking up for what she believes in -- people don't like that."

Harry and Meghan, however, have not let the tabloids take a toll on them. The two recently moved out of Kensington Palace and into their Frogmore Cottage ahead of Baby Sussex's birth.
