Kemper died at age 74 from brain cancer on April 9, at his winter home in San Tan Valley, Arizona, according to an obituary. He was the longtime owner and operator of Kemper Construction, "one of the oldest, multigenerational, family-owned construction companies in North Dakota."

"George's personality was as big as his laugh, and everyone knew to whom it belonged," reads his obituary. "Nobody got the last word in when you were around George because he just left the room when he was done talking."

Duhamel is dad to 10-year-old son Axl, whom he shares with ex Fergie, and he welcomed son Shepherd Lawrence with wife Audra on Jan. 11.
