Beyonce and Solange Knowles did not attend their father Mathew Knowles’ wedding on June 30.

Mathew Knowles recently wed his longtime love Gena Avery in a Houston ceremony on June 30, but the music mogul’s famous daughters, Beyoncé and Solange Knowles, weren’t there to bear witness to their dad’s nuptials.

“Unfortunately, Beyoncé and Solange had previous engagements which made it impossible for them to attend,” Knowles, 61, told US Weekly. Apparently the wedding had been planned for almost a year in advance.

While Solange performed at the Glastonbury Music Festival in England that night, Beyoncé did not have a show scheduled for her “Mrs. Carter Show World Tour.”  Instead Beyonce was found partying and drinking Champagne in a lounge.

The “Diva” singer’s absence raises questions of estrangement.  Mathew Knowles managed Destiny’s Child and Beyoncé’s solo career until she decided to cut ties in 2011, but the pop star said the decision to fire her dad was not a personal one.

Beyonce said that she and her father were on good terms, even after she fired him as her manager in 2011.
