Kicking off her week with some errands, Pippa Middleton took care of her to-do list in London, England this afternoon (April 15).

The gorgeous English socialite made her rounds and looked fabulous in a simple black sweater with dark wash jeans and black sunglasses as fans and shutterbugs looked on.

Pippa recently challenged London Mayor Boris Johnson to a ping pong match, and Johnson told press he’s a bit worried about his chances.

"I feel very nervous, clearly, because she seems to be very good. Well, she claims to be very good. But I'm very happy to do this because it's a chance to promote what we're doing with sports legacy London. We have greatly increased the number of people doing sports. If Pippa's kind offer can be used to promote that, then I'm all for it."
