Beyoncé and her sister Solange are both reported to have missed their father's wedding.
According to TMZ, when Mathew Knowles got married last week, neither of his daughters were present at the ceremony.
Knowles – who married Gina Avery after the pair were engaged for a year-and-a-half – told TMZ: "Unfortunately, Beyoncé and Solange had previous engagements which made it impossible for them to attend."
Their mother Tina Knowles filed for divorce from Mathew in 2009, and the couple officially divorced in 2011.
It was previously reported that Mathew was planning to sue UK tabloid The Sun over an article which claimed that he had become estranged from his famous daughter. The article also suggested that he hadn't yet met Beyoncé's daughter Blue Ivy.
The 61-year-old explained that he did give an interview to The Sun but suggested that the paper "knowingly and maliciously misrepresented [his] relationship with his daughter Beyoncé and with his granddaughter".
"My daughters and my family mean the world to me," he said. "The barrage of repeated falsehoods spawned by the British Sun's defamatory article has been exhausting and personally damaging to me.”
