I think they should get along well (especially if Chelsea's ever witnessed a near explosion and has the sense Georgiana might be sympathetic to at least some of the cause)
And it's less shit posting for its own sake than punching up. Chelsea has no interest in relationship or sex gossip or otherwise increasing stigma around non-normative behavior. But you best believe if so and so who spent more on swag bags for fundraiser attendees or their last vacation than they actually donated, Birdies ready to call them out.
