Miranda Lambert is not pregnant.

Bev Lambert, the singer's mother, told RadarOnline, "They are totally not expecting and I'm fairly certain that I would be the first person to know."

Last week, a "source" told Hollywood Life said that Miranda, "wants to slow down and focus on having a baby," after her summer tour.

Of course, wanting to "focus on having a baby" is very different than being pregnant.  But, you know how rumors get started.

Miranda Lambert and her husband Blake Shelton are not shy about sharing what's on their mind.  If they were having a baby, we believe they'd tell us.
