This week's Star Magazine features a story about Christina Aguilera disconnect with her husband, Jordan Bratman. Jordan wants the singer to SLOW DOWN. But Christina is a work horse and has no intention of doing so.

"I think Jordan is concerned- and has said so," an insider tells Star.

"But Christina has shown no sign of lightening her workload and fully intends to finish her tour [ending Aug. 3]. If she's feeling exhausted, she's hiding it. She's almost overcompensating, saying how great she feels to ease his worries, because the most important thing to Jordan is a healthy mama and baby. Christina has never done things traditionally. She's worried nonstop since she was a child. She's not about to sacrifice everything so she can ease Jordan's worries."

She shouldn't have any concern at this point. Doctors have told her (according to this source) that she is perfectly healthy and will have no issues carrying this child.

"Christina told Jordan that the doctor says it's totally possible for her to keep working and have a healthy, happy baby. But that doesn't mean Jordan is happy about it. Christina is the center of Jordan's world. He's naturally worried and overprotective. He's trying not to get angry with her, but he's probably frustrated that she can't see his point of view and at least cut back on her commitments a bit."
