"I was heavily pregnant, I couldn't drink - what is the point of having a 30th birthday if I couldn't get phenomenally drunk? But my husband took over, arranged a lovely lunch at one of my favourite restaurants, 20 of us, and they were all being so sweet, like, 'Look, you can have a great time and be sober!' Then they came back to our house... and they got completely obliterated (drunk)... And I was there eight months pregnant, completely sober. So it was lovely, but it wasn't what I'd imagined a 30th birthday was going to be." New mum Keira Knightley has mixed feelings about her sober 30th birthday party, which she celebrated in March (15). The British actress and her husband, rocker James Righton, welcomed daughter Edie in the spring (15).
