Elin, her twin sister Josefin and her husband, plus four other close friends have been staying at a luxury chalet in the French Alps. At the stroke of midnight New Year's Eve, they toasted the sisters' birthdays and wished for a better year ahead at a local restaurant owned by Swedes.
Elin and Tiger are used to spending their birthdays together. He turned 34 on December 30 but he hasn't been seen since the SUV crash that set his world upside down.
Since then, a parade of women have come forward and talked about affairs with the golfer.
