Pippa Middlton
Pippa Middleton attended Jamie Oliver's Instagram party.
The Duchess of Cambridge's sister joined the likes of Ronnie Wood Ashley Roberts, Eliza Doolittle and Boy George at the bash, which was held at Jamie Oliver's Fifteen restaurant in London on Monday night (16.09.13).
The 29-year-old socialite stole the show as she turned up in a black tulip skirt, baby pink jumper and a cream blazer, before she chatted away to the celebrity chef and was thrown into a fit of giggles.
The brunette beauty appeared to having a great time and despite recent rumours that her new boyfriend Nico Jackson popped the question to her earlier this month, she wasn't sporting an engagement ring at the event.
The couple have only been dating for six months but a pal close to Pippa previously said she was convinced she'd found The One and can't wait to tie the knot with him after seeing Duchess Catherine's and Prince William's wedding in 2011.
The source said previously "Pippa loved seeing Kate go down the aisle and now it is her turn for a fairytale wedding. She couldn't be more sure that Nico is the right for her. They are such a good fit for each other and their families get on really well. Everyone is so happy for Pippa."
