"Oh no I didn't," she said laughing. "You mean of all of the children?"
"Yeah," Bush deadpanned.
"No," she quipped.
Former President George H.W. Bush said he's always known and would tease his wife that she was "the most beloved woman in the world" and that he "had a complex about that fact".
In a statement released by Bush family spokesman Jim McGrath, the nation's 41st president says the outpouring of love and friendship following his wife's death "is lifting us all up."
He also referred to her as "The Enforcer," a term of endearment bestowed by her family.
Mr Bush says he has faith his wife "is in heaven, and we know life will go on - as she would have it." He adds: "So cross the Bushes off your worry list."
