If it's in a Christian church setting, then no, it is not allowed. Some denominations may allow it, but it is still inappropriate. The reason is because a Christian marriage is sacred as it involves God's presence in uniting the couple in marriage. The "star" of the show is not just the marrying couple, but the center is God in the process of unification. The couple essentially affirms with God with His plans for them as husband and wife, as well as creation of new life (children). "What God has united, let no man separate." It's far too different with parents and family giving their blessings to children. On the other hand, if it's a different setting, then it would depend on the couple getting married, the organizers, etc. They can decide for themselves what they want to include.
