Pippa Middleton has been on her best behavior since getting into a spot of trouble back in April.
On Thursday, Kate Middleton's younger sister, 28, looked demure in a white blouse and a navy skirt as she watched Serena Williams take on Hungary's Melinda Czink at Wimbledon (and shared a laugh with her younger brother James).
The former scene-stealing bridesmaid has been staying out of the spotlight since April, when she was photographed with pals in Paris -- one of whom thought it'd be funny to point a gun at the photographers who were following them. (An eyewitness reported them to police, though Pippa was eventually let off the hook.)
