deanefiresback.jpg After LeAnn Rimes revealed to Shape mag that she cheated on ex-husband Deane Sheremet because they got married too young and because their relationship wasn't "fulfilling," he's now firing back at the country star for her comments.

"Age had very little to do with why we got divorced," he tells Us mag. "I was very content and satisfied. I put myself on hold to funnel all my creative energy into her career and our marriage. I was willing to make the sacrifices necessary to have a successful marriage and further her career. I knew, and know, her better than anyone in this world."

Of his new lady love, Sheremet says, "I am happy now ... I didn't realize what I was missing and how much of myself was being neglected. I am very fulfilled in my life and work. It's a grounding feeling."

Judging by the glow on LeAnn's face these days, we're pretty sure she's much more satisfied with Eddie! At least everyone's happy now...
