Stevie and Sheryl's professional relationship has evolved into an amazing friendship. When Sheryl was diagnosed with breast cancer five years ago, she says Stevie was one of the first people she called. "Stevie was right up front," Sheryl says. "She's like, 'You are not dying of cancer. I'm proclaiming it right now.' I knew I wasn't, but it is a showstopper."

Today, Sheryl is happy to report that she's healthy and cancer free. "Five years is a great marker—it means I'm free and clear," Sheryl says. "And I want to encourage everyone to get mammograms and be diligent about that."

To encourage people to be proactive about their wellness, Sheryl recently co-wrote a cookbook, If It Makes You Healthy, with her personal chef, Chuck White. The cookbook is filled with more than 100 recipes that utilize vitamin-rich ingredients. "There's so much in food that also propagates staying well and can be a defense mechanism against cancers in general," Sheryl says.

In addition to singer, songwriter and cookbook author, Sheryl is also the mother of two little boys, Wyatt, who's almost 4 years old, and Levi, who is almost 1 year old. "They're road warriors," Sheryl says. "I think Levi was 2 weeks old when he started going on the road, and Wyatt was about 6 months. Wyatt started out in the bassinet in the studio when I was making the Detours record."
