Days after Tina Turner tied the knot
with longtime beau Erwin Bach, the couple finally held the celebration – a lavish, star-studded party Sunday at their lakeside estate in Switzerland.
, Giorgio Armani, David Bowie, Eros Rmazzotti and Sade were among the 120 guests, according to the Today show
and other news sites.
The couple's estate was reportedly decorated with 70,000 red and yellow roses from Holland. Men wore black tie to the event, and women were asked to wear white and beige.
Attendees participated in a traditional Buddhist water blessing ritual. Turner has been practicing the faith since the '70s.
Turner, 73, and Bach, 57, have been together for 27 years and have lived in Switzerland for more than 15. This is Bach's first marriage and Turner's second.
She divorced Ike Turner in 1976, and their tumultuous relationship was memorably portrayed in the 1993 biopic, What's Love Got to Do with It
