Beyonce fired her father as her manager in 2011 but insisted at the time that the split was amicable. She is currently in the midst of her "The Ms. Carter Show" world tour, but had a night off last Sunday, June 30, when the wedding took place, according to her website.

Mathew divorced Solange and Beyonce's mother, Tina, in 2011 after 31 years of marriage. He had been engaged to Avery for a year and a half, Us Weekly reports.
