The superstar and her husband kicked off their On The Run II tour last night.
Fans went wild when they saw new photos of Beyoncé and Jay Z's twins at the couple's show in Cardiff on Wednesday night.
Images displayed on screens at the concert showed Bey holding two babies, who fans presumed were Rumi and Sir.
The siblings, who turn one later this month, are rarely seen in public.

However, the singer's rep has now confirmed the babies in the photos aren't the Carter infants.
Buzzfeed reports that when reached for comment, asking if the children were indeed Rumi and Sir, the rep's swift response was, "It's not."
The mystery continues!
