Beyonce's dad and former manager, Mathew Knowles, put a ring on it today. Knowles wed ex-model Gena Charmaine Avery in a Houston ceremony. Missing from the celebration? The bride's new stepdaughters. "Unfortunately, Beyonce and Solange had previous engagements which made it impossible for them to attend," the groom (with a history of philandering) told TMZ. Do you think the DJ played “Single Ladies (Put a Ring on It)” during the bouquet toss anyway? Knowles and Bey's mother, Tina, divorced in 2011, the same year he and the singer ended their business relationship.
