The best response imo would be: I'd like to know. We should split a bottle of wine

Imo, wait for the response to the ,,Ooooh a princess. I'd be happy to slap the princess right out of you'' then hit with a re-engage after 2 days if you've gotten no response.
The takeaway should be the classic ,,I honestly didn't take you for the flakey type''. Brats...
