Cardi B Challenges Offset to Rap Battle The rapper is in it to win it. Cardi took to Instagram and challenged her own husband to rap battle on the TikTok app. She outlined the terms of the battle in her post. The loser has to buy all of the holiday decorations this year, for all of their homes. “Whoever loses gotta buy all the Christmas decorations, all of them. The one in New York, the one in Atlanta, too. What's up? Are you scared? Of wifey, hmm?" Cardi B, via Instagram If Offset accepts, the battle will take place at noon on November 29 via the TikTok app. Offset will release his highly-anticipated debut solo album on his upcoming 27th birthday, December 14. Cardi B has previously stated that the “very deep” album made her cry.
