Sheryl Crow, Wyatt CrowSheryl Crow is on diaper duty again! The singer/songwriter announced today that she has adopted a second baby boy.

"I have some exciting news to share with you guys," Sheryl writes on her website, "Wyatt has a new little brother!"

Levi James Crow was born April 30. Details of his adoption and birthplace are not known.

Big brother Wyatt Steven Crow (pictured above with his mom) was adopted in 2007. It was the silver lining to a cloudy year, as Sheryl had just gone through breast cancer treatment and had broken off an engagement to cyclist Lance Armstrong.

"There was a shift in my life when I got diagnosed, because it demanded I look at everything and redefine my life," the now cancer-free Sheryl told Page Six Magazine of her decision to adopt. "I always felt I would be a mom. I have strong ­maternal instincts."

Sheryl and her boys call Tennessee home, as they live on a farm just outside of Nashville. But all three of them will hit the road together on June 11, as Sheryl's publicist confirms with CNN that she does plan to take the boys on tour, including the first five dates of Lilith Fair.
