Serena Williams and her fiancé Alexis Ohanian are set to tie the knot in front of Beyoncé, Jay Z and Kris Jenner in their $1million wedding bash in New Orleans on Thursday

NEW Serena Williams and her fiancé Alexis Ohanian will have their wedding in New Orleans at the Contemporary Arts Center (inset) on Thursday. Among the 250 guests, Beyoncé, Jay Z, Kris Jenner and Ciara will be in attendance. The new parents planned their $1 million wedding celebration with such secrecy that even their A-lister guests won't know the exact location until Thursday morning. A source said: 'Serena and Alexis have spared no expense on their dream wedding. They have hired the best of the best and can't wait to get married in the Big Easy'. Attendees will be banned from using their cell phones at the event because Williams signed an exclusive deal with Vogue editor Anna Wintour to run the wedding day photos in the glitzy magazine.
