Award winning actress, Catherine Oxenberg, joins "Watch Over Me" as Leandra Thames, Michael's (Marc Menard) chief aide and personal assistant. Cold and efficient, Leandra is actually masking her unspoken love for Michael.

A New York native, Oxenberg grew up in London where her first Shakespearean acting coach was Richard Burton, who was engaged to her mother, Princess Elizabeth of Yugoslavia. She returned to the United States to attend St. Paul's School where she graduated Summa cum Laude and was admitted to Harvard University. Oxenberg transferred to Columbia University after deciding to pay her own way through college by modeling, and has graced the covers of Vogue, Glamour, Cosmopolitan, Harper's Bazaar, Redbook, Good Housekeeping, Los Angeles Magazine and Interview.

Oxenberg's acting career took off after landing her first audition to play Princess Diana in CBS TV's "Royal Romance of Charles and Diana." She was personally cast by Aaron Spelling in his hit "Dynasty," and went on to star in various television miniseries and movies including "Still Crazy Like a Fox," "Swimsuit" and "Trenchcoat in Paradise." Oxenberg has also hosted "Saturday Night Live" with Paul Simon.

For her feature film debut she starred opposite Hugh Grant in "Lair of the White Worm." Next, she starred with Jon Voight in "Boys Will Be Boys," "Arthur's Quest," "Time Served" "The Collectors" and "Catch Me If You Can" with Tim Matheson and the surprise independent film "The Omega Code," with her husband, Casper Van Dien. In 2002, Oxenberg won a Best Actress Award for her inspirational performance in the television movie, "The Miracle of the Cards," from the prestigious Movie Guide Awards.

Oxenberg and Van Dien have worked together on several different projects including a television series they produced and starred in titled, "I Married a Princess." Their production company, Holy Cow Entertainment, was founded with a unique vision to produce socially responsible, quality family entertainment with the intention of uplifting and transforming people.

Oxenberg and Van Dien currently live in Malibu with their five children.
