At the top of her career, Champa returned to the United States, starring in Steven Seagal’s Out for Justice (1991), followed two years later by Bernardo Bertolucci’s Little Buddha (1993), and then Don Juan DeMarco (1994) by Jeremy Leven. In 1998 she married an important Hollywood producer, influent member of the Academy, and gave him a son. Later in the 90s, she mostly worked for television guest starring in TV series such as Walker, Texas Ranger, JAG, and CSI: Miami. In Italy she has hosted the very successful fashion TV show for RAI TV, Kermesse. Champa has also served as special contributing editor and columnist for the Italian edition of Vogue and L’Uomo Vogue. Italian Vogue has written that, “She is an icon of Italian style.
