Before that party, he was spotted making new friends which included Australian model Sophie Taylor.
So who exactly is Sophie Taylor?
Sophie's mother confirmed media reports that the 24-year-old model had lunch with Prince William. I wish I could be there, but I've gotta go to work'.
"Sophie said they met and had a few drinks, "she added".
Everyone is talking about a new video of her husband Prince William showing off some rather freakish dance moves during what looked like a wild night out in Switzerland on Tuesday, March 14. William and his pals had skied to the restaurant, while the girls came up the mountain specially to meet them.
These duties included two investitures on behalf of the Queen, an India-UK cultural reception, the service unveiling the Iraq and Afghanistan memorial and Heads Together events with the Duchess of Cambridge and Prince Harry. "She is very down to earth and confident". According to Joni, her daughter was in a happy relationship with a young man called Aaron Goodfellow.
But her association with the royal has made Sophie an easy target on social media, where Joni revealed the model is being relentlessly "hounded" on Twitter by people from all over the world. "She is a great girl". And it's a shame because she's been targeted'.
The morning after her night out, Sophie posted a message to the Verbier Lost and Found Facebook page saying she had lost her phone during the night.
"She is such a girl on integrity", Joni, a resident of Wamberal, an affluent coastal suburb of the Australian Central Coast, told The Daily Telegraph.
The Prince showed he can get down with the best of them during a ski trip to Verbier.
Sophie previously worked for Australian agency Chadwick Models and relocated to Switzerland with Aaron several years ago after living in London.
According to her photographer friend Glen Krohn, Taylor is a down-to-earth girl who wouldn't be intimidated by the royals.
"Sophie is a great girl, a real down to earth straight talking girl from Oz", Glen continued. I'd never heard her mention anything about William or the royal family, but she would not be anxious about meeting them. She has posed for a number of topless pictures for the photographer, who described her as a confident person who does not have any inhibitions.
