Rihanna took to Instagram Tuesday to mourn her uncle Rudy.

The 31-year-old vocalist wrote, ‘RIP uncle Rudy!’ in a caption to a shot in which he was posed with her father, Ronald Fenty.

The Umbrella singer was inundated with thousands of responses from her 75-plus million followers, as fans offered their condolences over the death in the family.

The You Da One singer has had a complicated relationship with her dad in the past, suing him earlier this year over business maneuverings he had made, claiming he was misrepresenting himself as her agent while using the family name.

In court docs published on The Blast in January, the singer said her dad and an associate named Moses Perkins used the name Fenty Entertainment and tried to get paid pretending they could book her.

‘Although Mr. Fenty is Rihanna’s father, he does not have, and never has had, authority to act on Rihanna’s behalf,’ the Grammy winner’s legal team said in court docs.

The Barbados-born beauty said her dad was involved in deals – that she was not involved in and had no idea about – that would have seen her play shows in Latin America on a $15 million tour, and dates in Los Angeles and Las Vegas for $400,000, according to the outlet.

The suit came after numerous warnings to stop looking to trade on her name, she told the court.

Rihanna has past been open about her differences with her father, revealing in 2009 that she saw him abuse her mother Monica Braithwaite – and once broke Braithwaite’s nose. Rihanna said that her mother would not seek medical help in the incident and explained why.

‘Domestic violence is not somebody that people want anybody to know, so she would just hide it in the house,’ she told ABC in a 2009 interview, according to NBC Connecticut. ‘I always said to myself, “I’m never going to date somebody like my dad, never.”‘
