The back and forth debacle between Jackie Christie and her estranged daughter Ta'Kari Lee has been the major plot line for the recently wrapped season of Basketball Wives During the reunion special, the reality star was asked if she knew the birthday of Lee's son — her grandson.

When she admitted that she doesn't, her co-stars scoffed in disgust, with many saying this was proof that she does not hold them in the same esteem as the family members she boasts about. However, now, Jackie is explaining why she said what she said.
