Pippa Middleton and Her Boyfriend Canoodle in London

Kate Middleton's sister and Nico Jackson were spotted cuddling up in a cab after a fun night out Friday

Pippa Middleton and her boyfriend couldn't help but show their affection after a fun night out on the town.

Kate Middleton's younger sis and 35-year-old stockbroker Nico Jackson were spotted gazing lovingly into each other's eyes after attending the 50th anniversary party for Annabel's nightclub Friday in London.

Pippa, who sported a sparkly bronze mini dress to the affair, leaned in to kiss her beau as they held hands in the back of a cab.

Rumors swirled earlier this month that the 30-year-old party planner and Jackson, who have been dating for about seven months, are engaged, but Pippa still hasn't popped up wearing her supposed ring. 

According to multiple reports, regardless of Pippa's ringless finger, she's set to tie the knot next spring, but neither Pippa or Nico have yet to confirm (or deny) that speculation. 

In her latest column for the UK Telegraph, "Sport and Social" though, Pippa teased about her future wedding plans while musing about floral arrangements and her love for the New Covent Garden Flower Market in London, writing, "Maybe I'll be a DIY bride?"
