Jewel seems content to keep fans guessing about her rumored relationship with actor Kevin Costner .

The four-time Grammy nominee opened up about a variety of personal topics including mental health and motherhood in an Elle interview published online Wednesday.

When it came to her rumored beau, however, she remained coy.

Hes a great person, she said, adding that the public fascination is intense for sure.

Though the discussion of Costner ended there, Elle writer Melissa Giannini noted that Jewel was blushing while making the remark.
