The "Black Swan" star's husband Benjamin Millepied has accepted a job with the Paris Opera Ballet and the family will move to the French capital next year, reported Contactmusic.
Portman reveals she is already house-hunting and is even considering becoming a French citizen to complete her move to Europe.
"We're looking for an apartment. Benjamin and I are moving in autumn 2014 when his job at the Paris Opera Ballet starts.
It's obviously a massive change to quit Los Angeles for Paris. I don't know what my life is going to be like, but I'm so excited. I don't have the French nationality, but I would belove to get it.
The couple met on the set of Portman's Oscar-winning film "Black Swan". They married in August, 2012, three months after their son, Alef, was born.
