Meghan Markle certainly caused a stir when she took to her new Insta page, announcing her eight-part culinary adventure, set to debut on Netflix on Wednesday, January 15. The Duchess of Sussex's fresh series, 'With Love, Meghan', has got fans super excited as it's lined up with celebs straight outta Meghan's close-knit squad – they're talking about her former 'Suits' colleague, the lovely Abigail Spencer. Abigail, known for her role as Dana 'Scottie' Scott, which skyrocketed Meghan to fame, is among the 11 fab guests starring in the cookery show. There's this adorable sneak peek where Abigail's seen sampling one of Meg's mouth-watering sweet treats while they dish on their past. This begs the question: Just how tight are these gals, and what's the backstory? Well, get ready to dive into Meghan and Abigail's friendship history. Abigail, the Floridian beauty now 43, spilled some major love for Meghan, also 43, branding her as "one of my dearest friends" in a heart-to-heart with E!, reports the Mirror. She gushed even more, calling Meg “the most wonderful. One of my dearest friends. Cut to nearly 20 years back, the actresses first hit it off at an audition back in '07. Flash-forward to Abigail spilling tea on the Kelly Clarkson show last spring, revealing: "It was 2007, I was doing a pilot for NBC, and I went to read with the people who were supposed to play my best friend. They were testing other actresses. I walk in, I see this beautiful, gorgeous creature at the end of the table, and I'm like, 'Who is that?'" The spark was instant! She added with a twinkle, "We had an immediate something, you know? And her name is Meghan Markle." The star revealed her connection with Meghan, noting they discovered a special shared detail about themselves – their same birth date of September 4, 1981. Abigail excitedly shared with ET: "We were born on the same day, hours apart, in the same year. [Meghan is] a trusted friend and one of the most glorious people I have ever met." The two worked alongside each other on the set of Suits between 2011 and 2019, where Meghan portrayed Rachel Zane. During those years, Abigail was even a contributor to Meghan's lifestyle blog, The Tig. Abigail Spencer, known for roles in shows like Mad Men and Grey's Anatomy, spoke candidly about how she reacted when Meghan started seeing Prince Harry. She recounted during an interview for Netflix's 2022 docuseries Harry and Meghan: "I was screaming because I could tell it was different. It was very clear... That they were going to go to the ends of the earth to be together." At the lavish Royal wedding in May 2018 at Windsor Castle, Abigail was in attendance, stunning in a chic navy blue dress with distinctive white collar and cuffs, arriving alongside actress Priyanka Chopra. Always there for Meghan, Abigail has been open about the Duchess's experiences joining the royals, remarking on how Meghan shone during their 2018 Royal tour prior to the wedding. However, she has also observed the shift post-wedding, as the public scrutiny intensified and began to "tear" Meghan down. On the Netflix series, Abigail opened up about her own connection to royalty and Meghan's tough times: "That was a really dark time, and I didn't know what to do. I was not allowed to say anything. Anything that anybody was printing wasn't coming from anybody who knew her. There's all this untruth, there's all these lies, and it just seemed to be getting worse." And as for rumours of blue blood, when quizzed by Parade on any relation to British Spencers like Princess Diana, she joked: "That's so funny. My grandmother swears [we are], but I've never done any digging. I did meet a lot of Spencers [in England] and I am a Spencer, so who knows?"
