The good-looking duo stepped out together to attend the Sugarplum Ball at One Mayfair on Wednesday, Nov. 20 in London, England, where the twosome was all smiles, looking gorgeous as ever.
Prince George's aunt dazzled in a stunning floor-length black gown with intricate embroidery on the bodice and a semi-sheer skirt on the bottom of the dress. She added a sparkly cropped jacket and a pair of delicate drop earrings to her evening ensemble as she strolled in front of her handsome man.
Meanwhile, Nico mighty fine in a fitted tux, gently guiding his ladylove through the doorway while mesmerizing us all with his piercing blue eyes.
In September, rumors were swirling that Middleton's 35-year-old stockbroker beau had popped the question, but reports claimed the pair were keeping their engagement under wraps as they didn't want to take any attention away from Will, Kate and the royal baby.
However, the 30-year-old party planner has stepped out a number of times without a ring following the engagement speculation, despite multiple reports claiming that the younger sister to the Duchess of Cambridge is set to walk down the aisle next spring.
Neither Pippa nor Nico, who have been dating for about eight months, have yet to confirm or deny the reports.
There was no sign of any engagement bling on that finger when Ms. Middleton arrived at the Sugarplum Ball today, although the fashionista did add a delicate pinky ring to her glamorous look.
