Within hours of 'Dexter' stars Michael C. Hall and Jennifer Carpenter announcing their separation, rumors began swirling about what might have caused the split. One of the most popular? That 'Dexter' guest star Julia Stiles was secretly dating Hall.

Well, that's just not the case, says 29-year-old Stiles. In fact, UsMagazine.com reports she released the following statement on Thursday: "I have absolutely nothing to do with the split between Michael and Jennifer. We are good friends and enjoyed working together."

"This is a personal matter between them, and we should respect their privacy. Although I too prefer to keep my private life private, I felt compelled to dispel the rumors I was somehow the cause for this matter," she concluded.
