Dwyane Wade and Gabrielle Union share backstage selfie at Beyonce and Jay-Z gig

Dwyane Wade happily shared a smug backstage selfie with his wife-to-be Gabrielle Union at Beyonce and husband Jay Z's gig in Chicago on Thursday night.
But guests at his wedding next month will not get to do the same - the couple have banned invitees from bringing cameras and cell phones and using social media.
'Back stage after that #OntheRun concert... Chicago was on tonite,' the 32-year-old Miami Heat player bragged in a message accompanied by a photograph of himself with Union, 41.
 
Spotted: First Lady Michelle Obama, who Dwyane shot a commercial with earlier this year, was also at the gig along with her daughters Sasha, 13, and Malia 15
