Wie will become the second woman golfer to compete on The European Tour International Schedule. England's Laura Davies competed in the 2004 ANZ Championship at Port Horizons Golf Resort, Port Stevens, in Australia.
George O'Grady, Executive Director of The European Tour, said: 'Michelle Wie has demonstrated her outstanding golfing skills to a global audience as both an amateur and now as a professional, and we look forward to welcoming her to the Omega European Masters.
'The European Masters, formerly the Swiss Open, one of the most venerable events on The European Tour with a history going back to 1923, together with Omega, the highly respected title sponsors of the tournament since 2001 and now embarking on a new five year commitment, together made a formal request for Michelle to play.'
Stephen Urquhart, President of Omega, said: 'As a new member of the OMEGA family, Michelle is joining the ranks of some of the world's top golfers including Ernie Els and Sergio Garcia, who are recent winners of the Omega European Masters. By taking part in our tournament, Michelle will be able to match her golfing skills with many great players in the unique setting of Crans Montana.'
In her last two professional events on the LPGA Tour, Wie has finished in third place at the Fields Open in Hawaii and in a tie for third place at the Kraft Nabisco Championship - the first LPGA Major Championship of the Year.
Last week on the Asian Tour, Wie became the first woman since 1945 to make the cut in a top-tier mens international Tour event when she qualified for final round play in the 2006 SK Telekom Open in Korea. Wie also recently announced she will attempt to become the first women to play in the U.S. Open. She has entered a local qualifier in Hawaii on May 15 for the 2006 US Open.
