It looks like Catherine Duchess of Cambridge's little sister Pippa Middleton is still going strong with boyfriend Nico Jackson as the lovely couple showed off just how great their sense of style is when combined together.

On November 20th, the pair attended the Sugarplum Ball in London looking effortlessly chic and fashionable.

According to Us Weekly, Jackson wore a velvet black blazer and bow tie while Kate Middleton's sibling wore a floor-length brown gown with sheer black fabric over the top which featured detailed embellishments.

Pippa Middleton, 30, wore her brunette hair swept up and away from her face which allowed her to flaunt her giant silver earrings as she kept warm in a black cropped sequin coat.

The Vanity Fair columnist and her stockbroker boyfriend, 35, have been dating for eight months and are frequently spotted out spending time together. For sometime the couple was rumored to be engaged but a source insisted that the speculation was false.

Now that her so-called engagement is old news Pippa Middleton keeps the attention on her fashion.

Us Weekly reported that just last month the socialite made headlines for her choice of a cream-colored coat and lace "warm, blush oyster" hued shift dress for her attire to her nephew Prince George's christening.
