Mariah gets back to


The new Mrs. Cannon (aka Mariah Carey) can't lounge about on a honeymoon forever. The singer is expected back in NYC on Wednesday night to perform at Time magazine's Time 100 party. "She hasn't dropped out yet," an insider tells "As of right now, Mariah is still scheduled to perform, as had been previously arranged [before her quickie marriage to Nick Cannon last week]." If Mariah does indeed make the engagement, it'll be her first public appearance since her surprise wedding.
