The “lady friend” of David isn’t even the beginning of a rumor. It started here and here it stays. It’s basically one anon having fun going from Gillovny to Gorgans trolling them all out, testing the weakness of the firsts and the will to see David with anyone but Gillian of the seconds. Thankfully, no one with a brain will believe that.
The Italian article isn’t a proper interview either. It’s more an inside quote, like “she told me that”, which is necessarily twisted and rewritten because when you’re a journalist and you have a real quote, you use it properly, you don’t make her say what you want her to say to fit what you’ve read in the bad press. This journalist needed her to talk about love, which she wasn’t giving to him because hey, it’s Gillian and she doesn’t do that during interviews, so in my opinion, he made that up, which allowed him to mention PM. Click bait. If you ask the Italians in the fandom, they’ll tell you how not reliable this source is (and Italian press in general, Sorry! ;))

I guess people were expecting PM to attend this event because the guy she’s posing with, Robert Fox, is connected to The Crown as a producer. He’s a huge name in the U.K., and it just seems like Gillian is navigating in some new circle, with or without PM, with important people in the U.K. entertainment industry, which can’t be bad for her.
To me, it’s just reflecting what I thought in the first place when this rumor started. It’s all networking. And nothing else.
