The "How Do I Live" singer and Cibrian have been married since 2011, and she says it took time for her to get adjusted to their new blended family with his sons from his marriage to former model Brandi Glanville, reported Contactmusic.
"It takes a while, we're not exempt because we're in the public eye," Rimes said.
However, the family has found its rhythm and the 33-year-old singer is amazed by how much she is learning about life from her stepsons, Mason and Jake.
"They're fun. I didn't have a childhood, so it's amazing how much they're teaching me about having fun.
