Prince William, Kate Middleton's secret safari in Africa

London, Oct 23 (ANI): New pilot Prince William and his long-time girlfriend Kate Middleton apparently enjoyed a secret safari in Africa.

The couple went for the ten-day trip to Kenya to celebrate William passing his tough RAF helicopter search and rescue course.

It came just days after he completed his first mission in saving an offshore rig worker.

It is believed they returned to favourite destination Lewa Downs game reserve, owned by the family of the Prince's first love Jecca Craig.

"William worked incredibly hard to pass his training and couldn't wait for a break," the Sun quoted a source as saying.

"Both he and Kate love animals so Kenya was a natural choice," the source added.

The trip, which ended yesterday, will fuel speculation the couple, both 28, may get engaged after dating for seven years.(ANI)
