On Tuesday, the 31-year-old took to Instagram to share a series of images, including several affectionate snapshots with Nico.
In one photo, the events manager beamed broadly as she embraced her partner, while in another, Marina appeared elated as she enjoyed some music with her loved one.
It is unclear when Marina and Nico began dating, though the socialite was first linked to the cybersecurity Account Executive in 2023 when she posted a selfie with Nico to celebrate his 30th birthday in April of last year.
Additionally, Marina shared numerous images with friends, showcasing her distinctive fashion sense. For the much-anticipated Somerset festival, Marina sported a variety of colorful, boho outfits, including floral mini skirts, a flaming red scarf top, lime-green trousers, and a ruffled lilac dress.
She was accompanied by her sister, Lady Amelia, who made a bold statement in tangerine-hued baggy trousers, a bikini top, and a floaty purple ruffled top.
Captioning her snapshots, Marina penned: “Happy happy wonder filled fields”.
