Music producer Swizz Beatz dropped hints that his baby mama, Jahna Sebastian, is mentally unstable.
The Russian singer lashed out at Swizz's wife, Alicia Keys, in a lengthy Instagram post on Monday.
Jahna, who shares 9-year-old daughter Nicole Dean with Swizz, put Alicia on blast for "forcing" Nicole to call her "Umi," which means "Mother" in Arabic.
Jahna also bashed Alicia for allowing Nicole to have her own iPhone - which Jahna believes is inappropriate for a minor child. She said Alicia overstepped her boundaries as a stepparent by registering the minor child on the social media app TikTok.
Jahna noted that only the biological parent - not the stepparent - can register social media accounts for minor children.
But in a social media post, Swizz, 41, took the blame for supplying his daughter with an iPhone so she can keep in contact with her mother - and not call him.
In a follow-up post, Swizz told Jahna she knows his house phone number and she should call him if he wants to talk.
In a new Instagram post, Swizz, who is not a mental health professional, hinted that Jahna has mental health issues.
