Pippa Middleton and her boyfriend Nico Jackson were spotted getting cozy in the back seat of a taxi cab. The two got some heavy face time together as they stared deep into each other's eyes looking as if they were going to start kissing.

Kate Middleton's younger sister and her stockbroker beau attended the 50th anniversary party for Mayfair nightclub Annabel's where they were photographed leaving the bash in the early hours of the morning.

The Vanity Fair columnist looked as she had a few too many drinks and was a little dunk.

However, Jackson looked to be in great spirits as he wore a blue suit and was there to make sure his girlfriend entered the cab without any difficulties or wardrobe malfunctions, according to the Daily Mail.

The 30-year-old aunt of Prince George, who is the third in line to the throne, has been making headlines in the recent months as she has been attending society weddings, black-tie events and exclusive balls, not to mention her own engagement rumors are making top news.
