"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 wrote.
Rumors that the 36-year-old was engaged to Hollywood's most eligible bachelor began Thursday night after Alamuddin was seen wearing a sparkly ring while dinning at Nobu in Malibu with Clooney and Cindy Crawford.
Alamuddin is an international lawyer who has represented big names like Julian Assange.
News of Clooney's engagement comes almost two months after his latest ex-girlfriend, Stacey Kiebler, tied the knot to tech-entrepreneur Jared Pobre after months of dating.
