Elaine Irwin may be down, but she's not out.

After separating from John Mellencamp after an 18-year marriage, the 41-year-old model and face of Almay is ready to move on.

"The only thing certain in life is change itself," the mother of two told GlobalGrind.com. "Change is good, some would say it is our greatest teacher, and I am embracing it."

Mellencamp, 59, filed divorce papers last week. Since the split was announced, Mellencamp has been quietly dating Meg Ryan.
