Here's the lowdown on the former "Suits" star's strained family relations. She added that there are no paparazzi so it's really easy to just have a normal life where you are not getting dressed for the day and anxious about that element of it. Her mother, Doria Ragland, a social worker and yoga teacher, calls her famous daughter "Flower".
They've had practice already, as flower children (or Bridesmaids and Page Boys, in royal terms), for their maternal aunt Pippa's wedding this time a year ago.
Remi and Rylan Litt, 6 and 7, Meghan's goddaughters. His goddaughter Zalie Warren (the youngest, at two-years-old) and his godson Jasper Dyer are both included. Meghan is close to the family and has in the past spent Christmas with them.
After graduating in 2003 from North Western University with a degree in theatre and global studies Meghan moved back to Los Angeles and began working as a model and actress.
Then came the news of the heart surgery.
Half-sister Samantha Markle has also not held back in discussing Meghan and was even labelled a "vulture" by Piers Morgan for continually criticising the actor. Her soon-to-be niece, Princess Charlotte? Considering it was previously reported that Meghan and Harry will likely spend around $155,000 on their wedding day florals, chances are this is probably just a small sampling of the blooms that are going to be featured in Saturday's festivities.
Of course, Thomas Markle's decision could still change, so here's a rundown of everything that's happened so far.
I know, I know, we like the idea of Markle becoming a princess like in a Hollywood movie, but the way these royal designations work is complicated.
May 13 - Reports say Thomas Markle staged paparazzi photos.
In one of her most recent posts, a pyjama-clad Ivy is seen in a video reading a homemade Mother's Day card.
On Tuesday Mr Markle spoke to TMZ again telling them that his daughter had reached out to him and that he now wanted to travel to give her away.
Doctors "will go in and clear blockage, fix damage and put a stent where it is needed", Markle, an Emmy-winning Hollywood lighting director, was quoted as saying.
The very important kids remained a secret until Wednesday, when the palace officially announced who would be walking down the aisle before Markle at the royal wedding on May 19 at St. George's Chapel.
Samantha Grant, 53, suffered a possible broken ankle and fractured knee, according to her partner, Mark, who was driving the auto when the incident happened near their Florida, US, home on Wednesday.
Royal watchers are waiting for an updated official statement from Kensington Palace.
