It was back to work for Pippa Middleton as Prince William's sister-in-law was dressed professionally for a day in the office on Friday, and RadarOnline.com has all the photos.

Far from being a frumpy secretary, fashionista Pippa managed to look both stylish and sexy even in her conservative business attire while out in London.

Dressed in a gray dress covered in little hearts, a black blazer and flat ballet pumps, Pippa's fantastic figure could still be seen as she dashed to her car, no doubt keen to finally kick start the weekend.
