The Gossip Girl actress was spotted with Leo on a yacht in Cannes before traveling to Italy and then on to Saint-Paul in France, and said that she will never forget her time in the country.
'I went to Le Cordon Bleu for a few days a few months ago,' the 24-year-old actress told Japan's Movie Star magazine. 'I studied French in one language institution... It was an amazing trip I will never forget - a dream come true, and so many amazing memories made.'
Meanwhile, a source told Us Weekly that the couple 'are so smitten it's crazy', before adding, 'I bet they get engaged in the next six months.'
