MIAMI BEACH, Fla. -

Miami Heat guard Dwyane Wade is marrying his longtime girlfriend, actress Gabrielle Union on Saturday.

The couple has remained quiet about their nuptials, but TMZ has reported it will take place somewhere in South Florida.

According to Union's Twitter profile, the pair returned to Miami from Los Angeles on Monday. "Adios City of Angels... Miami bound," she wrote. "Countdown to #TheWadeUnion." 

The hashtag is already becoming popular in the days leading up to the big event. But don't expect family and friends to be using it during Saturday's festivities.

According to TMZ, Wade and Union have asked guests to leave their cameras and cellphones at home. A letter leaked to the website reads:

"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." 

Guests were also told to expect at least 30 minutes to go through security before entering the event. While it's still unclear where the reception will be held, the letter mentions that it is approximately 45 to 50 minutes south of South Beach.

Men were instructed to wear formal black; women are expected to be in formal white attire.
