Elizabeth Hurley managed to upstage the bride AGAIN yesterday as she stepped out in a stunning canary yellow dress and an over-sized cartwheel hat.

The 42-year-old looked the image of perfection as she left her London home today for the wedding of society writer William Cash and Venezuela-born socialite Vanessa Neumann.

While Hurley opted for summer brights, husband Arun Nayar and son Damian - who was a pageboy at the ceremony - opted for the more toned down shades of black and white.

Ahead of her wedding to former Spectator writer Cash at Westminster Palace, 'the Cracker from Caracas' attempted to settle her pre-wedding nerves by smoking in her bridal gown.

Cash, who claimed he is dramatically poorer after his 2007 divorce from Bulgari heiress Ilaria Bulgar, proposed to Neumann on New Year's Day in the exclusive Caribbean island of Mustique.

The 41-year-old son of Eurosceptic MP Bill Cash proposed to Neumann, 35, during a tropical storm.

Cash said: 'We were on our way to meet friends at the Firefly restaurant when I spontaneously proposed in the rain. It was rather romantic. Thank goodness she said yes.'

Neumann had a high-profile affair with Rolling Stone Sir Mick Jagger in 1999 and  broke off her engagement to Scottish landowner William Stirling - who also proposed in Mustique - in 2004.

Hurley famously upstage the bride at her friend Henry Dent-Brocklehurst's 1998 marriage to Hawaiian model Lili Maltese.

Hurley wore a slashed-to-the-waist red dress that clearly showed off her leopard-print knickers.
