Dwyane Wade marries Gabrielle Union on Saturday

Couple reportedly married at the Chateau Artisan

MIAMI – Miami Heat star Dwyane Wade married actress Gabrielle Union on Saturday at the Chateau Artisan mansion built to look like a castle, sources say.

Reports said Wade spent $5 million on the wedding weekend.

The couple kept wedding details top-secret, even asking guests to sign a confidentiality agreement. The agreement stated no cameras or phones were allowed. Those who violated the terms would be fined with cash fees, according to reports.

According to sources, the wedding was kept so private, planners had to title any paper work under "Sheik Noinu Edaw." If you read it carefully, that is Union Wade spelled backwards.

Sources also said the wedding's theme was "Old Florida juke joint," with plenty of references to the Heat.

Reports said the couple's guests were scheduled to be picked up from the Fontainebleau Miami Beach hotel in private buses enroute to the castle-like mansion.

The couple was scheduled to reach the venue by helicopter. Once everyone was on their seats, Wade and Union were said to tie the knot while John Legend played the piano.

The wedding was officiated by Union's best friend, actress Essence Atkins, according to reports.

Both Wade and Union have been married once before. Wade has three kids.
