The two are in Paris to promote their upcoming gay romance, "I Love You Phillip Morris."
At Monday's ceremony, French Culture Minister Frederic Mitterrand declared, "I love you Jim Carrey! I love you Ewan McGregor!"
He added that French moviegoers feel the same.
The film is based on a true story. Carrey plays a con man who meets the love of his life (McGregor) in prison, then comes up with elaborate escapes and masquerades to free himself and his man.
