I would guess dining room... but with them saying they are doing big dinner they would have to do it at her mom's. Guess its possible. Not seen them go into the dining room recently so who knows. They've been eatting their takeaways at the kitchen counter. Though may have moved her bedroom around and did it there. Honestly I don't pay that much attention to their house lolThey have those blinds throughout the bottom floor of the house, and there is no part of the office that has a wide expanse of white wall like what you see behind her. It has to be either the front living room or the dining room. And the only reason I'm even mentioning this is not because I actually care, but because it made me think about how easily any random stranger can know the entire layout and details of their home.
