R&B divas Brandy and Monica paid a visit to Power 105’s “The Breakfast Club” earlier this week to promote their new single “It All Belongs to Me,” their first collaboration in well over a decade.

During the extremely candid interview — which was hilarious, as always, thanks to hosts DJ Evny, Angela Yee and especially Charlamagne — the ladies addressed a number of topics, including Brandy’s brother Ray J, her relationship Kim Kardashian, the fatal accident she was in, and more, including the “beef” that separated Brandy and Monica for so long.

Charlamagne even made a comment about Brandy’s mouth that made her feel a bit uncomfortable. “I’ve never been this nervous a day in my life,” Brandy said.

Brandy and Monica also talked about the recent death of Whitney Houston, their respective financial situations, past relationships, cyber bullying and more. (Monica even touched on what is was like being stalked on Twitter, and how she was tackled backstage at a concert!)
