I was born in Ixelles on 15 January 1975. I spent my childhood in Grez-Doiceau (Wallonia) and my adolescence and student days in Brussels, before settling down in Sint-Genesius-Rode.
Following my degree in Applied Communication – Advertising at the Institute for Higher Social Communication Studies (IHECS), I became a financial officer at the European Commission and obtained a further degree, this time in Financial Management, through night classes at the Institut Supérieur de Commerce Saint-Louis. I then joined a law firm as a financial and economic advisor.
After being elected an alderwoman on Sint-Genesius-Rhode Municipal Council for the first time, I decided to focus completely on my work for the municipality. Pursuing my political activities, I was subsequently elected to the Flemish Brabant Provincial Council and then to the Chamber of Representatives (the lower house of the Belgian Federal Parliament) and the chair of the French-speaking liberal Reformist Movement party (MR) in the municipalities surrounding Brussels.
I joined the Federal Government on 21 September 2015, holding the role of Minister of the Budget and Civil Service, in charge of the National Lottery and Science Policy.
I have been the Prime Minister of Belgium from October 2019 to october 2020.
On 1 October 2020 I was sworn in as Deputy Prime Minister and Minister for Foreign Affairs, European Affairs and Foreign Trade, and Federal Cultural Institutions.
In July 2022 I became once again deputy mayor of Rhode-Saint-Genèse and in September I became a Member of Parliament.
