Decker recently opened up to Fox News about posting on social media — noting that she feels like she gives enough online and knows when to pull back.

"I give so much out, that I think that should be good enough," she explained while promoting her South Beach Diet partnership. "So whatever I'm sharing is what I feel comfortable sharing. And if I'm not sharing something, then it's no one's business."

"I feel I give enough out and if I'm not sharing something, then that's just something I choose to be personal about," Decker said.

The country music singer is married to former NFL star Eric Decker. The couple shares 6-year-old daughter Vivianne, 5-year-old son Eric and 2-year-old son Forrest.
