At this year's CMT Flameworthy Awards, Brad Paisley had nothing but loving words for his actress girlfriend Kimberly Williams as he accepted his award.

Now, the Nashville rumor mill is going crazy over the possibility that Brad and Kimberly are engaged -- but at this point, it is still a rumor.

Both Brad and his representation are keeping quiet about the subject -- when asked by a newspaper about Kimberly, all Brad would say is "She's great."

Could there be a wedding in the future? Stay tuned for details.
