Pandemonium erupted during Mindless Behavior’s jam-packed release week. After making appearances on “Good Morning America” and “The Wendy Williams Show,” music’s newest heartthrobs shut down the streets of Brooklyn with an impromptu performance at Basement Mix. Fans lined the block for a chance to meet and take pictures with the teen sensations as they promoted their debut album #1 Girl featuring the Diggy Simmons-assisted single “Mrs. Right.” Fire marshalls forced them to cancel a previous signing at FYE after thousands of kids showed up.

During their visit to “106 & Park,” Ciara called in to praise the quartet, who she collaborated with on the remix to “#1 Girl.”

“Those are my babies. This moment is all about them,” said CiCi. “I’m so excited for them. They’re such little superstars and I know it’s a big week for them—their first album is coming out—and I know how crazy that can be and how fun it can be.”

Watch Prodigy, Roc Royal, Ray Ray, and Princeton show off their moves while performing on “Wendy,” below.
