"Best friends forever, Me and Cube, going to be best friends forever!" Hart sang as the co-stars spoke with ET during a press junket for their upcoming comedy.
"We ain't best friends forever," Cube responded.
"We got our beards on because we are best friends," Hart argued, pointing out the duo's matching scruff. "I called you! I said, 'Are you cutting it or are you leaving it?' You said, 'I'm leaving it!' I said, 'Well guess what just grew!'"

While the 46-year-old Barbershop star denied his beard-based bromance with Hart, the 36-year-old comedian found a silver lining for his new beard.
"Now I got a new movie look," Hart explained. "Now you're looking at Kevin Hart, the action star."
The begrudging BFFs also opened up about their co-star Olivia Munn, who plays tough-as-nails detective Maya Cruz.
