Eva Longoria and Tony Parker are hoping that the number seven will bring them luck.

The “Desperate Housewives” star got engaged to the San Antonio Spurs guard in November after a two-year romance that had its ups and downs, and are planning to get married on July 7, 2007, because Parker thinks the date is lucky, according to Us Weekly.

“Tony is extremely superstitious and thinks 07-07-07 is the day most lucky to get married on,” a source told the mag.

The couple plans to get hitched at Château de Chantilly, a “fairy-tale-like” castle north of Paris, reports Us, which adds that designer Monique Lhuillier will create the wedding dress.

Longoria, 31, will head to France next month with event planner Mindy Weiss to work on details of the nuptials, along with 24-year-old Parker’s mother, Pamela. “Tony wants [his mother] to feel that it’s her day as well as his and Eva’s,” a source told the mag.

Longoria’s rep would say only: “She’s still working out all the details. Nothing is confirmed.”
