The Suburbicon actor, 57, spoke to Entertainment Tonight Thursday night about his babies at the American Film Institute’s 46th Life Achievement Award Gala Tribute in Hollywood, California. “Yesterday was their birthday. They are 1 year,” Clooney told the outlet, admitting that his kids weren’t as psyched about the festivities due to a bit of jet lag and “slept” during cake time. “They’re kind of on Europe time, so they were sleeping during most of the day,” he added. “So we had a cake waiting, and we’d wake them up and show it to them and then they’d go back to sleep.” Want all the latest pregnancy and birth announcements, plus celebrity mom blogs?
