Her dad and former manager Matthew Knowles got married in Houston on June 30, and he told press that both Beyonce and her sister Solange were unable to attend the big day.
"Unfortunately, Beyonce and Solange had previous engagements which made it impossible for them to attend," her dad said in a statement.
Matthew divorced Tina Knowles, the girls' mother, back in 2011.
The wedding was on a Sunday but Jay-Z's wife is in the middle of her Mrs. Carter World Tour. She performed in Los Angeles on June 28 and Las Vegas on June 29, while Solange played the Glastonbury music festival that weekend.
Do you think it's rude that his daughters didn't attend his nuptials or do you think he understands that they were both working?
