True Detective star Michelle Monaghan and legendary swimmer Michael Phelps shared the winner's trophy at Omaga’s inaugural Celebrity Masters in Switzerland.

The celebrity nine-hole golf match was held yesterday and followed on from the main event at the Omega European Masters in Crans-Montana.

It featured eight stars of sport and screen, including champion surfer Rob Machado, England cricketer Kevin Pietersen, Swedish Ice hockey star Peter Forsberg, England rugby giant Mike Tindall, actor and comedian Rob Riggle and star of Gossip Girl Ed Westwick.

The talented celebrities were split into four teams of two.  

Participants competed in a “best ball scramble” format with Par as their friend (meaning that Par will be the maximum score on each hole) and the team with the most birdies crowned champions.

All players competed for their own selected charities with Omega making donations on their behalf. 

At the event, Phelps played on behalf of the Michael Phelps Foundation, while Monaghan supported the US charity Baby 2 Baby.
