Actress Katherine Heigl, known for her roles in movies like "Knocked Up" and "27 Dresses", doesn't see herself as a "difficult" actress.

The star has been previously blamed for reportedly causing difficult situations on the sets of "Life As We Know It". But she insists that she conducts herself as "professional and respectful" in Hollywood, reports femalefirst.co.uk.

Asked about her reputation, the 35-year-old actress said: "I can't really speak on that. I can only say that I certainly don't see myself as being difficult. I would never intend to be difficult."

"I don't think my mother sees herself as being difficult. We always...I think it's important to everybody to conduct themselves professionally and respectfully and kindly. If I've ever disappointed somebody, it was never intentional."

The former "Grey's Anatomy" actress hopes fans will "be excited about" her return to television.
