The battle between Jackie Christie and her estranged daughter Ta'Kari Lee became a major topic of conversation during the upcoming Basketball Wives season six reunion special.

While plenty of tea has been spilled — and sides have been taken — over this mother-daughter drama during the past season, there were audible gasps from Jackie's co-stars and on social media when it was revealed that Jackie does not know her own grandson's (Ta'Kari's son's) birthday.

It all started when Jackie and Evelyn Lozada, who have been at odds for the majority of the season, spoke about Evelyn donating toward Ta'Kari's son Jaxson's medical expenses after his publicized health scare.

At the time, Ta'Kari asked for help on social media, claiming that Jackie had abandoned her years ago and they were currently estranged. She explained that she needed help for his burn scars that he has been suffering from, and Evelyn offered to help.

"Jaxson is one," Jackie said when asked how old he is, but when asked to specify his exact birthday, she replied, "I'm not sure." Damn.
