While it was reported yesterday that Serena Williams and Alexis Ohanian were tying the knot in NOLA, it turns out that was just the rehearsal dinner and the actual wedding is taking place this weekend. Guests from Kim Kardashian to Kelly Rowland were spotted arriving to the dinner last night with an interesting accessory in tow — a Yondr phone pouch. 

Seems like the “no pictures” policy the tennis champ instated for the wedding was also the case for the rehearsal. Yondr allows venues to create phone-free spaces by guests placing their phones in the pouch that locks while within the event’s perimeters thanks to a force field. Guests maintain possession their phone the entire time and can unlock the case outside of designated area. Other big celebs like Dave Chappelle and Alicia Keys used the device to prevent fans from recording their performances. Pretty high-tech for a wedding, no?

Well, when your wedding pics are promised to Anna Wintour for a spread in Vogue, you do the most to make sure they stay exclusive.
