"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 firm said in a statement on Monday.
Alamuddin, 36, joined the firm in 2010 and later became a member of its international law team. The chief executive of the firm, Robin Jackson, added his personal congrats as well.
"She brings a bright light to everything she is involved in," he said. "And I am so delighted at her happy news."
Clooney's mother, Nina, was reportedly excited over her son's engagement as well. "'You can say I'm extremely happy, Amal's a lovely girl,'" she told the U.K.'s Daily Mail. "We weren't at all surprised when they told us they were engaged, and we couldn't be happier for them."
While a rep for Clooney, 52, has yet to confirm the engagement, a source close to the situation says the actor and Alamuddin are just trying to keep things "very low-key."
"I think it's like they want the people they love to know that this is real," the source says. "That they plan on being together forever."
