Via US Weekly:
The R&B superstar, 31 — who is headlining the big event on Feb. 3 at the Mercedes-Benz Superdome in New Orleans — will be joined onstage by her Destiny’s Child bandmates Kelly Rowland and Michelle Williams, multiple sources confirm to Us Weekly exclusively.
…the “Crazy in Love” singer will open the much-anticipated show solo; midway through her performance, Williams and Rowland will appear onstage and launch into a short medley of the group’s hits, culminating in a brand-new song, “Nuclear,” their first original material in more than eight years.”
