She continued: “Thing is, I’d spent all my friends as godparents on my first child, so Billy had 11 godparents. And so I thought I could make up for Nell ― you know, who suddenly came along and we didn’t have any left. I thought, ‘Well, if I give her Prince William that would cover,’ you know?”
But it seems the prince wasn’t ready for the responsibility. “He just said, ‘You don’t want me to be godfather to your child.’ And I left and obviously it didn’t work out. Funny enough,” she said.
Speaking to the Daily Telegraph recently, Bonham Carter revealed she's adopted Princess Margaret's no-nonsense nature since portraying her in the show. 'Princess Margaret has seeped into me. I’ve just done a huge press tour. I was much firmer on boundaries and less tolerant of people’s behaviour. I thought: "Margaret".
'I’ve always been so amenable to people. But now I just say: "No that’s enough," to people who are wanting to take photos all the time... Very firm. Very PM,' she said.
