Someone get them a room!
After celebrating Annabel's 50th anniversary party in London, the two were spotted doing some full on canoodling in the back seat of their car.
Pippa is clearly a woman who knows what she wants because she leaned all sorts of in for a smooch on the lips! And we wouldn't be surprised to hear that she got what she wanted!
Perhaps these lovebirds are just practicing for their big day??
