London, March 21 : Prince William has taken girlfriend Kate Middleton to the Alps for a skiing break, suggesting that their on-again, off-again relationship is back on track.

Also, William's father, Prince Charles, will soon be jetting out to the exclusive resort of Klosters to join the happy couple.

Sources say that the arrival of the Prince of Wales can be seen as an indication the pair is stronger than ever and even planning to get engaged.

The young royal and Kate have been together in the snow covered setting of the Swiss alpine resort.

Sources say that the two looked every bit the happy couple having rekindled their romance, reports the Telegraph.

William and Kate dispelled rumours that their romance is on the rocks by barely leaving each other’s sides as they tested out their skiing skills.

Kate looked smart in black and white as she mastered the runs at the resort where their on-off relationship became public in 2004.

She was accompanied by an armed Scotland Yard detective from the security detail assigned to Prince William. (ANI)
