The future Mrs. Clooney was spotted Monday in London, looking stylish in a white top, brown slacks and a camel-colored trench coat.
The two were first romantically linked in October when they looked cozy at a dinner party, while presumably bonding over their shared concerns for global human rights.
Clooney popped the question to Alamuddin last month.
The lovebirds celebrated their engagement at a star-studded Malibu bash on Mother's Day.
They plan to wed in September, according to the Daily Mail.
