Meghan Markle's best friend has arrived in London days before the royal wedding.
Jessica Mulroney was spotted at London's Heathrow Airport along with her husband, Ben, and their three children,7-year-old twin sons Brian and John and 4-year-old daughter Ivy, who are part of the wedding party.
In the days leading up to highly anticipated nuptials, a source tells ET that Meghan is leaning on her friend for support.
The two first met when the Meghan relocated from Los Angeles to Toronto to film Suits. Mulroney, a stylist and PR specialist, dressed the 36-year-old actress, and has also styled Canadian Prime Minister Justin Trudeau's wife, Sophie Grégoire Trudeau, and Cityline host Tracy Moore.
In January, it was reported that Mulroney flew to London to help her friend pick out her wedding dress. This is right up her alley as she assisted Meghan with choosing the wedding dress she wore on an earlier episode of Suits. Mulroney is also a consultant for the Canadian outpost of the bridal boutique Kleinfeld's.
In addition to Mulroney, Meghan's Suits co-stars are also making the trip across the pond. Gabriel Macht, who plays Harvey Spector the USA Network series, and his wife, Jacinda Barrett, who has been a guest star on the show, posted photos from their time in London.
