SAN DIEGO -- NBA superstar LeBron James' top-secret wedding will be at the Grand Del Mar this weekend, a source told San Diego 6.
Celebrity gossip websites have struggled to find information about James' upcoming wedding to Savannah Brinson, the mother of the basketball stars' two boys.
One possible reason? Employees and others involved with the wedding were asked to sign non-disclosure agreements, the source said.
Jay-Z and Beyonce are among the stars on the guest list for the exclusive event in the Los Peñasquitos Canyon Preserve, according to a source involved with the set-up.
A large tent has been erected outside the luxury hotel and resort. An after-party will take place on a different part of the property, the source said.
According to the couple's save-the-date invitations, the wedding will take place Saturday afternoon.
