The actress married basketball player Dwayne Wade at the Chateau Artisan castle, Miami on Saturday in a black-and-white themed affair.
Gabrielle wore a bespoke Dennis Basso gown, featuring an oversized bow at the back, to walk down the aisle. She completed her wedding day look with a flowing veil and a bouquet of white roses.
In the evening, the Bring It On actress, 41, changed into a sleek embellished gown with a sweetheart neckline and low-cut back.
"Thank you thank you thank you @DennisBasso for helping me design THE most perfect gowns for the most special night of my life... So grateful... So happy" Gabrielle captioned the picture, before adding "#TheWadeUnion" to a snap of Dwayne, his three boys, and herself.
Her new husband Dwyane looked handsome in a customised suit by Dsquared2 – a brand loved by Madonna, Britney Spears, Justin Timberlake and Lenny Kravitz.
To complement the groom, male guests were given black bow ties designed by Dwayne, with a message that read, "Please help Gabrielle and Dwyane to 'tie the knot' by wearing this hand-selected custom Dwyane Wade For The Tie Bar bow tie to the wedding."
Celebrities sharing in the couple's happy day included the groom's fellow Miami Heat player Chris Bosh and his wife Adrienne, Kim Kardashian's good friend Jonathan Cheban and filmmaker Will Packer.
John Legend was also on hand to perform for the newlyweds.
Gabrielle took to Instagram before the wedding to post a series of photos of her and her fiancé, including one of them arriving at dinner in a black Ferrari, and another of Gabrielle showing off her amazing figure in a black, halter neck jumpsuit.
