The Duchess of Cambridge jetted out to Pippa Middleton's secret hen do while Prince William was 'dad dancing' at another ski resort.
Kate had her own party with her sister and friends in Meribel, France, at the same time her husband was being filmed 'raising the roof' and busting othermoves on the dancefloor 100 miles away in Verbier, Switzerland.
The couple had travelled together in the same private jet, which was paid for by the Middletons, the Daily Mail reported.
It quashes the suggestion that Kate was at home looking after babies George and Charlotte, while Wills partied hard.

A friend told The Sun: "Pippa loves skiing so it was her first choice for a hen weekend.
They stayed in a really exclusive catered chalet with maids and chef, who ensured that they were totally spoilt.
"The owners also wanted to impress their royal guests so the girls were showered with gifts.
"They were given Swatch watches, Ugg slippers, leather-bound notebooks and bespoke fragrances. It was a very small, private party and they had an amazing time."

In an embarrassing series of videos, the 'worse for wear' Prince William, 34, was seen letting loose with some 'dad dancing' while partying with friends at Farinet nightclub in Switzerland.
The second in line to the throne was then seen turning away from his friends and familiarly putting his hand on a woman's waist, before leaning in to talk to her.
The woman is believed to be Australian model Sophie Taylor, 24, who William was seen high-fiving on the side of the slopes.
In further footage, the father-of-two was cutting some shapes while wearing a woman's hat, as a blonde woman danced nearby.
The future king also shared an emotional hug with the club DJ after going into his private booth while was on the decks.
The numerous clips emerged after William was criticised for skipping a major Commonwealth event to go on the skiing holiday in Switzerland.
The Duke of Cambridge - who has previously been accused of being 'workshy' - was one of the only key members of the Royal Family who did not attend the event at Westminster Abbey, despite the occasion having deep personal resonance for the monarch.
It revived criticism that William is failing to knuckle down to his royal role.
