Zara Phillips' plunging dress

Britain's Zara Phillips caused a stir at a charity ball by showing off her ample bosom in a very low-cut dress on Wednesday (21.11.07).

The 26-year-old royal accessorised her figure-hugging blue Robert Cavalli dress with a cowboy hat and boots for the Red Cross Ball at London's The Room By The River venue.

Zara was accompanied to the Honky Tonk Blues themed bash by her rugby star fiancé Mike Tindall, who donned a western bootlace tie, jacket and black hat for the event.

While the royal may have drawn some disapproving looks for her risqué dress, Mike, 29, did not seem to have any complaints, and the pair openly kissed and canoodled at their table.

A source said: "They couldn't keep their hands off each other and they didn't care who saw. Mike looked very proud to have such a good-looking woman on his arm."

Other guests at the ball included Girls Aloud singers Kimberley Walsh and Cheryl Cole and actress Joan Collins.

Meanwhile, it has been confirmed Zara will receive her Member of the Order of the British Empire (MBE) at London's Buckingham Palace next Wednesday (28.11.07).

The sports star - who was voted the 2006 BBC Sports Personality of the Year - will be presented with the honour for her services to equestrianism after she won both the European and world eventing titles last year.
