Adding that this is all George's parents will be commenting on the news, he explained, "It's their day."
News broke Saturday that the notorious bachelor, 52, proposed to his lawyer girlfriend, Amal, 36. The couple was first rumored to be dating in October 2013.
Though Clooney's rep has no comment, Amal's law firm, Doughty Street Chambers, confirmed the news Monday with their own statement.
"The barristers and staff of Doughty Street Chambers offer their best wishes and congratulations to Ms. Amal Alamuddin, a member of Chambers, and Mr. George Clooney on their engagement to be married," the statement said.
And clearly, her co-workers have nothing but praise for the British beauty.
"Amal Alamuddin is a brilliant and passionate defender of human rights who has put in the enormously hard work necessary to improving them," said Joint Head of Chambers, Geoffrey Robertson QC, who has worked with Alamuddin on such high-profile cases as representing Julian Assange, head of WikiLeaks. "She is respected and admired by all her colleagues."
