The Keeping Up with the Kardashians star got her very first presenting job on the Fox reality competition's second season alongside former Saved by the Bell actor Mario Lopez.
Kardashian opened up about the experience of working on a high-pressure show like The X Factor during an interview on Thursday's Good Morning America.
"It was so fun! It was my first time ever hosting anything, especially on live TV. I felt like with every show I got better and better and my confidence [increased]," she declared.
The star added: "At the very last show I was like, 'Wait, I'm just getting in the groove!' And it's over!"
Kardashian has previously said she would like to return to The X Factor next season, but has admitted she's had no offer yet.
Good Morning America's Elizabeth Vargas also asked Kardashian to weigh in on who could possibly replace departing judges LA Reid and Britney Spears.
"I was hired a week before the show aired, so I feel like Simon [Cowell] might do the same thing," she predicted, adding: "He loves the suspense."
Her X Factor co-host Lopez has publicly expressed hopes that he will be invited back when Fox premieres season three this fall.
