Actress Gabrielle Union and her fiancee Dwyane Wade have banned cell phones and cameras from their upcoming wedding.

The Bad Boys II star is set to marry the basketball player on 30 August (14) in Miami, Florida, and an invitation, obtained by TMZ.com, reveals security at the bash will be tight.

Guests will meet at a local hotel before being transported to an undisclosed location for the wedding, and they have been asked to allow "at least 30 minutes to process through security at the venue".

They are instructed to leave cameras and cell phones behind to "protect our privacy" and bring along photo identification.

Guests have also been asked to dress in formal attire with all men wearing black, and women in white.
