Iggy Azalea, 30, is “so excited to celebrate Onyx’s first Christmas with him,” a source close to the “Personal Problem” rapper EXCLUSIVELY tells HollywoodLife. It has been half a year since Iggy announced that she “has a son,” whom she welcomed with her ex Playboi Carti, 24, and Iggy has already gone to work to make her first Christmas with the baby boy “special” — even if she had to change up some plans.
