Chip Wilson, the billionaire founder of Lululemon, is facing a potential shake-up of his estimated $6.1 billion (£4.6 billion) fortune after filing for divorce from his wife of 20 years without a prenuptial agreement.
The legal separation proceedings, filed in the Supreme Court of British Columbia by Wilson, 71, and his long-time business partner, former lead designer Shannon 'Summer' Wilson, 52, could split one of retail's most lucrative fortunes.
