I don’t know what Portofino was, it could be what you said. The thing is David is and always will be territorial with Gillian no matter who’s she’s dating. And same for her. All her previous partners had to deal with it, but I’m not sure PM will be that easy and chilled about that. I guess we will eventually see the three of them at the same event, so we will see.
It’s possible PM will hang out a little bit on the set, but The Crown starts filming in November, so he should be busy and won’t bother us too much I think. I hope.
