Tamara Ecclestone turned her mansion into a lavish ski chalet for her father Bernie's surprise 85th birthday bash.

The 30-year-old socialite, with the help of her sister Petra, transformed her London property to look exactly like the billionaire's chalet in Gstaad, Switzerland on Saturday (17.10.15) to host his party in celebration of the milestone.

The brunette beauty covered the outside of her home with red brick to give the impression of cabin wood panelling, while the paved driveway was sprinkled with fake snow.

Christmas trees, spray-painted white, were stood up outside the entrance, while the inside was just as impressive.

Artificial animal heads were mounted on the walls and faux fur covered the seats and cushions, according to MailOnline.

A lavish spread was laid on for the guests and the Formula 1 boss was handed a large birthday cake, with the white icing emblazoned with multiple pictures of his face over the years.

Tamara took to her Instagram account the day after the celebratory bash to give fans an insight into what went on during the party by bombarding them numerous snaps.

Alongside a photograph of herself, her sister and their famous father, she simply wrote: ''A night to remember.''

She later uploaded a shot of Bernie - whose birthday falls on October 28 - cutting his huge cake with a large silver knife.

And it seemed the party continued on into the morning after for the youngsters as they were given guided donkey rides around the lavish £70 million estate in the affluent area.
