I think it makes sense. Some of Brick’s post sounds pretty childish and even if I’m not a fan of Brad, I’m sure he’d do that in a more clever way. I don’t think he has that kind of time either because this dog is tweeting all day long. Monique has access to Brick to take pictures and I’m pretty sure she has a lot of free time in her hands. She also looooves social media and interacting with David’s fans (side-eye). So yes, It makes sense that it’s her.
