To start the new year right, country superstar Wynonna Judd has signed on to become the face of Alli – the over-the-counter weight-loss product that first hit stores in 2007.
"This is about me picking something that I know works for me," Judd, 44, tells PEOPLE. "I can still plan [my work] and not feel like Alli is dictating my life as I have in the past on other programs. It fits into my schedule."
And a busy schedule, at that. Along with raising her kids Elijah, 14, and Grace, 12, Judd is set to release her new album on Feb. 3 and embark upon a 2009 tour.
"I don't have diet goals," says Judd, who started taking Alli last September. "My goals are to live as happy and healthy as I can."
She also intends to motivate fans. By taking her weight-loss journey public, "people can see themselves in me and say 'You know what? If she can do it, I can do it,' " says Judd.
"I hope people will be inspired by the fact that I've overcome a lot, I'm still here and it's a miracle."
