Showstopping bridesmaid: Paris Hilton ensured she wasn't overlooked as she arrived in St. James's in a racy black evening gown for her sister Nicky's pre-wedding party on Thursday evening
Despite being on hand to support Nicky, Paris, 34, couldn't resist putting on a show as she arrived at the event.
Dressed to impress in a black sequinned gown, the reality show regular showed off her tanned legs thanks to the dress' daring thigh-high split.
She lapped up attention outside Spencer House, where the bash was held, posing for photographers as a cascade of super-cars pulled up to drop of the well-heeled revellers.
Speaking about what she would wear for bridesmaid duties, Paris previously said: 'It's her day so whatever she wants me to wear, I will.
'But I know that Nicky has impeccable taste so the bridesmaid dresses are going to be beautiful.'

Nicky and James have been dating since 2011, and the wealthy Brit proposed last August while visiting Italy's Lake Como.
Speaking about her desire to lay on her nuptials away from her native US, Nicky explained: 'I’ve always wanted a destination wedding and I love London, so I’m leaning towards London.'
They will exchange vows in The Orangery at the palace, close to the London residence of Prince William, Duke of Cambridge and Catherine, Duchess of Cambridge.
This will actually mark the second wedding for Nicky, who married childhood friend Todd Andrew Meister in Las Vegas 10 years ago, only for the marriage to be annulled three months later.
