The prestigious Trophee Chopard awards for rising actors were handed out by the evening's guest of honour, Cate Blanchett, who quipped of the recipients, "I have an inappropriate crush on both of them."
Upon accepting the award, Blue Is The Warmest Color star Exarchopoulos replied to Blanchett, "I am happy you have a crush on me. I have a crush on you, too."
Exarchopoulos and Percy Jackson star Lerman were chosen by a jury which included top movie boss Harvey Weinstein and director Atom Egoyan, among others.
Previous recipients of the Trophee Chopard include Hayden Christensen, Shailene Woodley and Jonathan Rhys-Meyers.
