News of Carrie Underwood's baby bump may be upset with reports of impending divorce, according to sources.

Carrie Underwood's baby bump has been confirmed with a due date last September, when the "American Idol" winner announces she's expecting the bun to come out of the oven in Spring.

The formal confirmation (or hint) of her pregnancy was teased in her Instagram account, where she posted a photo with her two dogs wearing shirts printed with "I'm going to be a big brother" and "I'm going to be a big sister."

Carrie made an appearance in The View last month with the announcement, beaming with a wide grin to boot.

News of her pregnancy is dampened with rumors of a troubled marriage with Nashville Predator player Mike Fisher, though. Sources report the couple's relationship is recently strained to the point of considering a divorce.

The Star reports the couple's marriage is now more strained with the baby bump due, and the singer is ready to give Fisher the ultimatum to stay or get out.

"Carrie has always done the cooking cleaning and the laundry...but it's harder for her to keep up, now that she is pregnant. Her schedule is also extremely busy, and it's starting to take a toll on her...She gets bouts of morning sickness and is tired all the time." (classicalite.com)

Carrie is reportedly going on a hiatus of several months; her tour is put on hold with only a couple of commitments scheduled; she's still confirmed for the CMA gig on July 2015. Apparently spending more time at home and in domestic life may put more stress on her pregnancy, being around Fisher.

"Carrie constantly asks [Mike] to help out more, but he's just oblivious to it. It's gotten to the point where she's starting to resent him, and the stress isn't good for the baby."
