According to the network, it was the first time since March they had been able to leave home for anything "properly social."
Kennedy said that asking her grandmothers to be her bridesmaids was a way to help make the ceremony even better for them.
"If they're going to come, we wanted to make it as special as we could for them," Megan said.
