Meghan Markle has been quite helpful for Kate Middleton during her difficult pregnancy

The Duchess of Cambridge is only a couple of months away from her due date.

Meghan Markle and Kate Middleton's friendship continues to grow as the date for the royal wedding approaches. And now, reports of Meghan Markle helping her future sister-in-law have come to the surface, showing how closely the two ladies have bonded over time.

At seven months, appearing regal can be a royal pain. Plagued by the same severe morning sickness she endured with both Prince George, 4, and Princess Charlotte, 2, the 36-year-old has nodded in agreement as well-meaning friends “have told her it gets easier every time,” says a family insider, “but I think she’s found it challenging. It’s taken quite a toll.”

It was reported that the Duchess of Cambridge struggled at the early stages of her pregnancy. In fact, she missed a lot of royal engagements due to severe morning sickness or hyperemesis gravidarum. But now, it's a good thing that Markle is there to make things better for Middleton.

Middleton and Markle are living near to each other at the palace. Prince Harry's fiancée makes use of this to visit Prince William's wife from time to time to share a cup of tea or offer some healthy tips.

"She shares tips she's read about healthy eating," a source told Us Weekly.

Kate’s charming prince, 35, dotes on her as well. “William does all he can to make sure she’s comfortable,” says an insider. “He just wants her to feel supported.” Initially, Middleton and Markle were often compared as both had a great influence in fashion. But despite the comparison, they have maintained a good relationship.

In fact, during Prince Harry and Markle's first joint TV interview, the royal prince revealed that the Duke and Duchess of Cambridge were "longing" to meet the "Suits" star. Markle said that the royal mom was "wonderful."

Middleton and Markle are expected to work together. The Duchess of Cambridge will reportedly be the Horrible Bosses star's mentor. Middleton will help Markle adjust to royal life when she officially becomes one.

With the arrival of late April, when she’s set to welcome her third heir, Kate will have more helpers in waiting. As they did with George and Charlotte, she and William plan to draft a few baby nurses for the first six to eight weeks, “mostly to help with establishing a sleeping routine,” says a source.
