Dancing queen: Pippa, wearing a plunging red Temperley London gown, struts her stuff on the dance floor
She arrived and left the event with her devoted long-term boyfriend.
However, when it came to doing a turn on the dance floor, glamorous Pippa Middleton was more than happy to be entwined with another tall, handsome friend rather than partner Alex Loudon.
Miss Middleton – wearing a plunging red Temperley London gown, golden clutch and matching stilettos - strutted her stuff following the final bout of the Boodles Boxing Ball, which features a number of amateur bouts, earlier this month.
At one point, beaming Miss Middleton, 28, was swung round by her mystery partner before he lifted her high into the air.
The event – which took place at the Park Plaza Hotel in central London on October 1 and where a table of ten cost £1,950 – raised money for charity. However, these informal photographs were only posted on the event’s Facebook page in recent days.
Miss Middleton’s elder sister, The Duchess of Cambridge, had been a guest in previous years.
Those who joined Miss Middleton at the event this year included former Spice Girl Geri Halliwell as well as Princesses Beatrice and Eugenie.

Prince Harry’s former girlfriend Chelsey Davey and Jecca Craig – a former girlfriend of Prince William’s – were also amongst the 850 guests.
Miss Middleton has been dating Loudon, 31, for 10 months.
And despite having a different dance partner, she and Loudon - a former professional cricketer turned financier – proved their relationship remained very much on as they enjoyed a lingering kiss while waiting for a taxi after leaving the event at 4.30am.
