Did JAY-Z & Beyoncé Renew Their Vows? New Video & Photos from On the Run II Tour Shows Ceremony with Twins

Did Beyoncé and JAY-Z just hint to their fans that they renewed their wedding vows?

In a video taken at their On the Run Tour II kickoff show on Wednesday in Cardiff, U.K., both musicians can be seen on a screen in all-white attire joined by 6-year-old daughter Blue Ivy and 11-month-old twins Rumi and Sir for what appeared to be a vow renewal ceremony.

The message “THIS IS REAL LOVE” is projected during the film at the concert as the power couple sings their 2009 duet “Young Forever.” In April, they celebrated their 10-year anniversary together.

Before Bey and Jay shared the footage of the ceremony, photos of the pair holding two babies was shared along with the words “LOVE IS UNIVERSAL” and “LOVE NEVER CHANGES.” The Bey Hive presumably thought the children are Rumi and Sir (who will celebrate their first birthday on June 13), however, the babies are not.

“At the end of the show the Carter babies were included in a family collage [however] he babies in the film clip at the beginning were not their children,” a source tells PEOPLE.

“Rumi and Sir Carter debut on #OTRII!,” tweeted one account, while another wrote, “THE TWINS. GEMINI LEGENDS.”

Fans first saw the twins one month after their birth, in a family portrait featuring the proud mom holding her babies and introducing them to the world.

“Sir Carter and Rumi 1 month today,” Beyoncé, 36, captioned the image — the style of which was reminiscent of her double baby announcement the previous February.

The couple is famously private when it comes to their children, but in January, JAY-Z couldn’t help but rave about the newest additions to the Carter crew.

“We are in a beautiful time now because they are 7 months and they can’t move,” the 48-year-old rapper joked in an interview with CNN’s Van Jones. “They can just coo … they just coo and you don’t have to, ‘Wait, wait, wait, wait.’ ”

He continued, “You know, they’re not running anywhere yet. We are going to enjoy these couple of months until they start running, and then it’s over.”

Beyoncé and JAY-Z announced the tour in March and early buzz led the couple to release nine new tour dates just a week after the original announcement. The tour now includes 15 European cities and 29 North American performances.

A source previously told PEOPLE the couple has brought along all three of their children, revealing, “It took a lot of work to make this [joint tour] happen. It’s the best choice for their family.”
