The human-rights attorney, 39, wore a vibrant red, ankle-length overcoat with a minidress, black tights and motorcycle boots while on her way to a salon in London.

Multiple sources confirmed Amal’s pregnancy with husband George Clooney to PEOPLE earlier this month, revealing that she’s due this spring. The babies are the first children for both.

The couple have been spending time in the U.K. over the past few months, quietly nesting at their renovated English mansion in a small town in the countryside west of London.
