The couple had previously been spotted sitting behind the Duke and Duchess of Cambridge in teaser footage for the event, as the audience enjoyed a performance from musical star Ellie Goulding.
In a new photograph from the event, Beatrice and Edo are spotted donning facemasks as they pose in front of a Christmas tree.
Property developer Edo wears a smart suit, complete with a matching tie and pocket square, while his wife sports a camel coloured coat.

Beatrice wears a burgundy velvet knotted headband – something which has become a signature look for the royal – to keep her hair from her face, and also sported a patterned facemask.
The couple appeared glowing and happy, despite any lack of sleep they may be experiencing in the run-up to their first Christmas with their new baby.
The couple welcomed their daughter Sienna Elizabeth Mapelli Mozzi on September 18 and shared the happy news on social media at the time.
Sharing a snap of their baby’s footprints, the couple expressed their delight at their new arrival and how well five-year-old Christopher Woolf, known as Wolfie, Edo’s son from a previous relationship, was adjusting to life as a family-of-four.

“We are all doing well and Wolfie is the best big brother to Sienna.”
No official photograph has been released of the young tot, but the family were spotted enjoying a festive day out last month when they visited Winter Wonderland in Hyde Park.
Beatrice was spotted pushing Sienna in a £1,000 Fox 3 Bugaboo pram as she and her husband navigated around the festive attraction.

They stopped for food at a German bratwurst stall in the attraction’s Bavarian Village and sat on wooden benches outside the food stall to consume large hotdogs and hot drinks.
For the chilly weather, Beatrice wore a fur-lined parka coat with a teal scarf and black bobble hat.
Edo wore a similarly low-key weather appropriate outfit, opting for a green flat cap, and casual red-and-white trainers.
Beatrice and Edoardo posed for socially distanced wedding photos last summer
The couple tied the knot in a private ceremony at Windsor last summer, with a relatively small guest list thanks to Covid restrictions in place at the time.
For the ceremony, Beatrice, the eldest daughter of Prince Andrew and Sarah Ferguson, wore a vintage gown by designer Norman Hartnell, which was on loan from her grandmother, the Queen.
For her big day, the princess also wore the Queen Mary diamond fringe tiara, which Her Majesty wore to wed Prince Philip in 1947.
The couple posed for socially distanced portraits with the Queen and Philip, in a move that saw them adhering to government guidelines in place because of the ongoing pandemic.
