Pippa Middleton: Sugarplum Ball with Nico Jackson!

Pippa Middleton and her boyfriend Nico Jackson look elegant while leaving the Sugarplum Ball on Wednesday evening (November 20) at One Mayfair in London, England.

The event was also attended by English model and socialite Poppy Delevingne.

While rumors were swirling earlier in the fall that Pippa and Nico were engaged, she is still not showing off a ring on that finger yet. Only time will tell what the future holds for these two!
