Britain's Princess Beatrice has told friends her boyfriend is "the one".

Beatrice, 19, is said to be "more in love than ever" after returning from a romantic break in Morocco with 25-year-old marketing man Dave Clark, who works for Sir Richard Branson's Virgin Galactic Space Tourism project.

Sarah Ferguson, the Duchess of York, and her daughter Princess Beatrice attended a memorial service for fashion editor Isabella Blow yesterday.

The royals joined a crowd of almost 1,000 for the service at London's Guards Chapel, to pay tribute to Isabella, who committed suicide in May, aged 48.
