All good things must end. The much-talked about affair between Jemima Khan and comedian Russell Brand, described as `tiger ride`, has reportedly come to end too.

With her impressive social connections and elegance, Jemima always seemed an unlikely catch for Brand. And romancing each other for a year, the pair has gone their separate ways, reports dailymail.co.uk.

A source said: `The relationship has simply run its course.`

During their time together, Jemima, 40, and Brand, 39, regularly appeared at society events in between tête-a-têtes at the city's best restaurants and walks with Jemima's beloved white Alsatian, Brian.

There was even talk of a wedding on the horizon. But sources close to Jemima's family confirmed that she is single once more.

Neither side was keen to speak about the break-up, although friends claimed that Jemima was the driving force behind the couple's final split last month.

In a sign of the times, they have now 'unfollowed' one another on Twitter. This could suggest a whiff of acrimony, although Jemima has always remained friendly with her ex-flames, including Hugh Grant and her former husband, Imran Khan.

Some family members are said to see the split as the end of a `tiger ride`.
