Foster and McPhee are parents to son Rennie. In October, the pair spoke to PEOPLE about their son's newfound musical talents.

"We think [he'll be musical], but we don't know," Foster said at the time. "Kids, strangely, will do something for a while and then it'll amaze you and then they just drop it and they don't do it anymore. So we don't know if the drumming thing is here to stay — I'd rather he have a tennis racket in his hand than a drumstick to tell you the truth. But anyway, if he ends up being a drummer, that would be great too. He loves watching our drummer, JR Robinson."
