In an interview with GQ, the former Friday Night Lights actress stated that she and the New York Yankee have no pressing desire to tie the knot.
"I promise you, I'm not getting married in the next month," she said.
Kelly went on to assert that she's established her own identity separate from her relationship with the athlete.
It was reported last September that she frantically called Jeter after arguing with a flight attendant about allowing her dog to sit with her in the plane's first class section.
The star explained of the incident: "Do people think that somewhere in my brain, I think Derek can save me from someone telling me my dog can't fly? If that's the way I worked, he would have left me a long time ago."
She will next star with Leighton Meester in The Roommate, which is released on February 4 in US cinemas.
