Nicki Minaj has called on her Barbz fan base to handle a young woman who entered a group chat to interact with some eager Nicki fans, which apparently left the rapper frustrated this afternoon. On Monday (Dec. 21), Nicki Minaj shared the phone numbers of several unsuspecting fans via Twitter after it appears that Nicki was added to a group chat called "MOM CLUB." After posting an image of the conversation, the Young Money Entertainment signee encouraged her fans to respond to the members of the aforementioned text chat. "Barbz, have no mercy," she tweeted while sharing eight different people's contact information.
