Fresh from her whirlwind trip to New York Pippa Middleton showed no sign of jet lag as she arrived at London's exclusive Arts Club ready to dance the night away.

The Mayfair members club is the hottest place to party for celebrities and London's elite and Pippa fitted right in wearing an electric blue dress, fitted leather jacket and suede shoe boots.

Pippa and friends had dined at the Little House restaurant – another upmarket London nightspot famed for it's silver mugs of cocktails – before heading across the road to the club where they rubbed shoulders with celebrities Jessie J, Sophie Ellis Bextor and husband Richard Jones, JLS and Ultimo boss Michelle Mone at the luxury bar.

29-year-old Pippa was in Manhattan last week to meet with publishers of her new party book 'Celebrate' which is billed as a guide to 'creative entertaining'.

But the socialite managed to mix business with a lot of pleasure on her transatlantic trip as she was spotted taking in the tennis at the U.S. Open, shopping on Fifth Avenue and rollerblading around Central Park as well as celebrating her 29th birthday.

The brunette was also rumoured to be apartment hunting after she was spotted on upmarket Madison Avenue entering a residential building and the photo agency that snapped her described her as 'a realtor'.

Pippa and her friend had to brace themselves against the windy September night

If Pippa is pitching herself as a
party expert then last night was a surefire way to cement her
credentials as queen of the social scene.

Arriving
in a taxi with a beautiful blonde friend Pippa spent several hours at
the Little House restaurant and bar, the latest outpost of the trendy
Soho House group, before heading to the Arts Club, known on the scene as
the only place to go for after hours drinks.

And
it looks like the Chelsea girl has been taking style tips from New York women, as she ditched the nude tights favoured so much by her big sister
Kate and braved the chilly September evening with bare, bronzed legs.

hair too was in stark contrast to sister Kate who is failing in her
fight against the frizz during her humid trip of the Far East

She chose a block bright knee-length dress which she toughened up with a black leather jacket and chunky fringed shoe-boots.

A leopard print clutch and bright red nails added a dash of fashionista and she finished the look with simple smokey make-up.

Also
at the Arts Club – which costs 2000 to join and has an annual
membership fee of 1500 – was Jessie J looking cool in a pair of silk trophy trousers, Michelle Mone and Sophie Ellis Bextor and husnabd Richard Jones taking a nighty off
from their new baby.

Pippa's party book is described as a cross
between a party planning bible, entertainment guide and recipe book', nd it was reported last month that she has negotiated a six-figure book
deal with publishers Michael Joseph, the branch of the Penguin Group
that deals with ‘highly commercial’ properties.

As well as featuring four times on the cover Miss Middleton has insisted on writing the book herself and hopes that it will cement her credentials as a party planner as well as earning her a small fortune in the process.
