Jessica Simpson has babies on the brain.

"Dreamt that I had a son named Tenacious D.... That was a strange one," the 30-year-old singer wrote on her Twitter page Sunday.

Simpson, 30, who got engaged to former football player Eric Johnson in November, has never been shy about her desire to have children.

Last year she told the ladies on The View, "I can't wait to have kids. If I don't have kids by the time I'm 40, my best friend Ken Paves and I are going to have children."
