R&B singer Fantasia Barrino.

R&B singer and “American Idol” season three winner Fantasia Barrino is reportedly in a custody battle over her 13-year-old daughter Zion with the girl’s father, Brandel Shouse, according to TMZ.

Shouse claims that Barrino is an unfit mother, although he has publicly admitted to abusing her in the past, the gossip website reported. Shouse has allegedly not been in his daughter’s life, despite both living in North Carolina.

Shouse and Barrino were high school sweethearts and were together for five years before parting ways in 2003 over Shouse’s alleged violent outbursts.

“Despite living in North Carolina, Mr. Shouse had very little personal contact with Zion and has provided no financial support for her,” a representative for Barrino told S2SMagazine. “Fantasia hopes that her fans understand the sensitive nature of these matters and that she cannot share with them all of the details at this time.”

The case is not scheduled to appear in court until next year. Barrino also has a two-year-old son, although she has not identified the boy’s father.
