Princess Beatrice was joined by her stepson Wolfie as she and husband Edoardo Mapelli Mozzi as the royals attended their annual Christmas Day church service.
Christopher Woolf, known as Wolfie, is the son of Bea's millionaire husband and his ex Dara Huang, who she previously called her 'bonus son'.
The couple largely keep him out of the royal spotlight, and before today had only been seen at the late Queen's Platinum Jubilee celebrations.
