Cherie Blair and Cilla Black turned shepherd for an afternoon and herded goats across London bridge in a stunt to raise awareness for International Widows day.
According to the Loomba foundation, which organised the event, the farm animal is a life-line for many widows in South Asia and across Africa.
You have to be kidding me? Cherie Blair with one of the goats
The charity walk with the goats was allowed because Lord Loomba, who is head of the charity which organised the event, exercised his right as a Freeman of the City of London to herd livestock over the bridge.
Cherie Blair, president of the foundation, told the BBC that "this year we wanted to highlight the fact that a goat can bring an income to a widow."
The event gave rise to some unusual pictures (see slideshow below). Can you come up with a caption?
