Meghan and Harry's latest sighting comes just a few hours after the former Suits star released a statement regarding her father, Thomas Markle. He was originally intended to walk his daughter down the aisle, but will no longer be attending the nuptials due to health issues.

"Sadly, my father will not be attending our wedding," Meghan announced. "I have always cared for my father and hope he can be given the space he needs to focus on his health."

"I would like to thank everyone who has offered generous messages of support," she continued. "Please know how much Harry and I look forward to sharing our special day with you on Saturday."

The father of the bride, who lives in Mexico, told TMZ on Wednesday that he was alert and out of heart surgery he underwent earlier that morning after suffering a heart attack over a week ago.

Thomas originally backed out of the wedding earlier this week after he was accused of staging photos for the paparazzi. He reportedly changed his mind and was hoping to attend the church service at St. George's Chapel after all, pending approval by his doctor.
