June 9, 2012 (Los Angeles, CA) -- Matthew McConaughey and his longtime girlfriend Camila Alves will finally tie the knot this weekend, and ENTERTAINMENT TONIGHT has the exclusive Texas wedding details!

The theme of the wedding is "island beach meets Texas" with yellow and orange colors. Preps began two weeks ago: In the nuptials area of the Austin, TX, property there are wispy long white tents, and in the other section there is a Texas theme. Horseshoe pits, fire pits, washer pits and tether ball were all installed for the big day, and the entrance and walkways were enhanced with landscaping. 

Estancia Churrascaria, a Brazilian steak house, is catering the wedding with a menu that includes Brazilian top and bottom steak, chicken wrapped in bacon and pork sausages with cheese bread. The gaucho chefs are wearing tapered black pants with blue shirts and red bandanas around their neck. Staff including waiters in black pants and white shirts began to show up at 5:50 p.m. -- they waited in their cars until being picked up by golf carts. Sheriff's deputies also were positioned around the property to provide security and check in guests. 

Matthew got in shape for the wedding after flying back from France this past Thursday by taking a one-on-one private Pilates session at Body Business in Austin.  He does private Pilates instruction three to four times a week and also sees a personal trainer at this same facility.

McConaughey and Alves got engaged over the holidays. The couple have two children together, 2-year-old daughter Vida and almost 4-year-old son Levi, and began dating back in 2006.
