A union for Gabrielle Union! The actress and her basketball player love Dwyane Wade tied the knot on Saturday, Aug. 30.

The power couple exchanged vows in Miami at the stunning Chateau Artisan castle in a black-and-white themed affair. The bride wore a custom Dennis Basso gown from Kleinfeld Bridal. Celebrities in attendance included Miami Heat player Chris Bosh and his wife Adrienne, filmmaker Will Packer, Portland Trail Blazers player Dorell Wright and his wife Mia, Survivor alum Corinne Kaplan, actor Kevin Hart, reality star Jonathan Cheban, and singer John Legend, who performed.

Many of the details for the big day were decided by the groom, Union revealed to Ellen DeGeneres this past February. 

"Secretly this is his princess moment," she joked of her love's wedding planning joy. "He has waited for this for a long time. He's been hoarding bridal magazines. He's very ready… Every aspect — aspects I didn't even know went into wedding planning — he is on. To have a centerpiece or not have a centerpiece? He has very strong opinions. No centerpieces. Who cares? He does!"

Wade, 32, proposed to Union, 41, in December 2013, after dating for four years. The Heat baller gave the Being Mary Jane star a stunning 8.5-carat cushion-cut diamond ring. 

Wade announced the couple's wedding plans via Instagram right after his December betrothal, sharing a photo of his fiancée's hand with the sparkler, and captioning the shot, "She said YES!!!"

The lovebirds have been very vocal about their affection for one another throughout their romance. 

"She makes my eyes sparkle," Wade told Oprah Winfrey on Oprah's Next Chapter in July 2012. "The biggest time she makes my eyes sparkle is when [my son] Zaire comes home and homework is a little hard that day, so he's stressing, and she goes to the table with him and she sits down until he gets it. At that time my heart is smiling a little bigger that day because I know her love is deeper than just me."

This is the second marriage for Wade, who was previously married to his high school sweetheart Siohvaughn Funches from 2002 to 2007. It is also Union's second marriage, as she was wed to NFL player Chris Howard from 2001 to 2005.
