Janet Jackson was worried enough about her son being with his father that she called police, according to TMZ.

She was reportedly concerned that her estranged husband Wissam Al Mana had been using drugs around their child. She’d also reportedly been warned about allegedly aggressive behavior by a nanny who was there.

According to ETOnline, Jackson made the request so authorities could check in on her one-year-old son with the billionaire businessman.

Jackson’s brother Randy informed ETOnline the nanny was “terrified by his behavior and locked herself in a bathroom, so she could contact Janet.”

Police arrived at the Nobu Hotel in Malibu around 10 p.m. on Saturday (June 2) to conduct their check. They reportedly didn’t find anyone in danger.

Jackson and Al Mana have been separated for a little over a year. The former couple has opted to co-parent their child.
