The pair have started to spend more time together and performed a duet in a recent episode.
"I love where my relationship with Will has gone," Jones told Give Me My Remote. "I love that we're buddies. I love that. I love that they went that route with that.
"I was a little nervous about doing the song that I did two weeks ago, but I felt so much more confident and relaxed because Matt [Morrison, who plays Will] was doing it with me."
Jones, who said it is "a pleasure and an honour" to work on Glee, also revealed that she would like to work with the female cast members more.
"I loved when the girls were playing football," she said. "Loved it. I love working with the boys, they're all fantastic and all such sweethearts. But I'd like to work more with the girls."
Glee airs on Tuesdays at 8/7c on Fox in the US and on Mondays at 9pm on E4 in the UK.
