Maroon 5’s latest hit “Girls Like You” spent weeks atop music charts, but it wasn’t until the star-studded music video came out that lead singer Adam Levine was aware of just how successful the song had become.

“With the powerful imagery that the video presented, along with the song and sort of the dual meaning that the lyrics had, I felt like it was just a special moment that we had kind of happened upon,” Levine said during his recent Variety cover shoot.

There’s another reason why Levine thinks “Girls Like You” became a smash. Maroon 5 recorded a version of the single with Cardi B.

“She was in the honeymoon period of her moment,” Levine said. “It was just beginning to be that female artist that everybody was talking about, and I thought it was an important thing for her to be involved. I knew she would have an interesting take on what was being said, and she would do it in a way that you wouldn’t necessarily have thought of.”
