Kate and Pippa 'closer than ever' after gun-waving incident

Kate Middleton has been giving her sister tips on working in America, after embarrassment over a gun-waving incident in Paris.

Pippa Middleton reportedly infuriated royal officials when she was pictured next to a friend waving a gun as they drove through Paris in April but she and her sister - who were pictured at the Wimbledon tennis final together earlier this month - are now said to be closer than ever.
