Katie Holmes and Jamie Foxx has reportedly decided their wedding venue. According to Radar Online, the "Dawson's Creek" alum is beginning to prepare all the lavish details regarding her wedding to Jamie.

An insider tells the site, "Katie will always remain loyal to her roots in Toledo, Ohio, and she's pouring millions into renovating her vacation house [on the shores of Devils Lake in nearby Michigan]." According to the source, Katie is prepping the luxury property where "she wants to get married."

While the home is "officially for her parents," the extensive renovations are definitely of the A-list type, says the site.

The insider adds, "Katie is turning it into a self-contained secure retreat and she plans on spending a lot more time there in the future with Jamie and her daughter Suri. She loves that house and there's no doubt her obsession with the Kennedys has influenced the design and plans for this the house. It will be the perfect place for a wedding."

Jamie was spotted wearing a suspicious gold band on his ring finger when he was about to jet off to Atlanta on March 2. Katie also showed off a big sparkler on her ring finger while stepping out in NYC on March 17.
