Jessica, who has been friends with Meghan since her time as an actress on Suits, will be helping out married couples with their second weddings after their disastrous first attempts.
The series, which is currently in production with Netflix and CTV for US and Canada, will be ten 30-minute episodes and set to air later this year.
CTV said in a statement that there were no plans for Meghan on the show, tweeting last week: “The Duchess of Sussex does not appear in upcoming @CTV series.”
Jessica is a professional stylist rumoured to have worked on Meghan’s wardrobe with her when she first became a royal, getting in touch with designers and asking them to dress Meghan.
A source told People at the time “She emailed the designers on the future royal’s behalf and arranged for a selection of pieces to be sent to Kensington Palace.”
Jessica’s children Ivy, Brian and John were also bridesmaids and page boys alongside Princess Charlotte and Prince George at Meghan and Harry’s wedding.
