Beyoncé & Jay-Z kick off 'OTR 2' tour in Cardiff #snapshots

Power couple Beyoncé and Jay-Z kicked off their 'On the Run II' tour Wednesday in Cardiff, Wales. They chose the moment to unveil their adorable infant twins, Sir and Rumi Carter via a backdrop.

The A-listers performed more than 40 hits during their two-and-a-half hour concert. At the end of the concert, Bey thanked everyone for coming. "Thank you guys for sharing this beautiful night with us," she said. "It feels so good to be on stage with the one I love." 

Next stop? Glasgow, Manchester, and then London before they head off around Europe. I hope the day goes well for fans attending the Glasgow gig tomorrow. Forecasters are warning bad weather with thunder and lightning, but apparently this should die out as the evening continues.

According to Beyoncé's representatives, these are NOT the actual twins:

However, it was confirmed by Bey's mother Tina that the image below are the real twins of Sir and Rumi:
