Dwyane Wade and Gabrielle Union's save-the-date video leaked online and shows the moment Wade proposed (with the help of his sons) and the family's celebration. The 50-second clip was sent out to guests and reveals that the wedding will take place in Miami, Fla. on Aug. 30.

TMZ previously reported that Wade and Union have a script rule banning cell phones and cameras from the ceremony.

"For the comfort of our guests and to protect our privacy, no cameras or cell phones will be permitted at the party. Also photo IDs will be required for all guests," the wedding invitations read, according to TMZ.

In June the "Think Like a Man Too" actress talked about wedding planning to US Weekly and said she wasn't really involved in the process.

"We're pretty deep," she told US about the planning. "And by we, I mean [Dwyane] and the wedding planner. I'm at work. He realized that I was trying to turn it into a frat party with k-cups and beer pong, and he took over. He really Kanye'd himself and really doubled down, and it's his princess day and I'm just along for the ride."

 Back in February the 41-year-old revealed that she is insisting on the two sign a prenup before walking down the aisle. During an appearance on the "Arsenio Hall Show," Union said the prenup was her idea because she needs to "protect her stuff."

"For this marriage, the biggest difference between this and the last marriage will be a prenup. At my insistence. At my insistence," Union said. "When you have your own stuff, you don't need to worry about anyone else's stuff. So everyone should go into the relationship knowing, 'I'm here for you and you're here for me.' And the reality is I've never seen Dwyane balance a checkbook, so I gotta protect my stuff... It's the wave of the future."
