Carrie Underwood and her husband, Mike Fisher, may have looked happy and in love at the 2014 Billboard Music Awards in Las Vegas Sunday, but the twosome’s union might not be as peachy as it seems. For the fourth time in recent months Carrie Underwood is rumored to be planning to welcome a child in an effort to save her marriage to the retired NHL star.

Similar to previous reports released in March, ShowBizSpy.com published claims Monday that Underwood, 31, has allegedly agreed to conceive a child in order to appease Fisher, 33, despite the country crooner’s desire to continue her entertainment career. “She realizes a baby is the only thing that can save their marriage,” a source told the gossip site.

According to ShowBizSpy.com, the “Good Girl” singer and her athlete beau recently sparred over their pregnancy plans after the country star confessed to considering several acting opportunities offered to her earlier this spring. Following the announcement, Underwood reportedly realized Fisher was “ready to throw in the towel on their relationship” and has since made a promise to try for a baby by the end of 2014.

“Mike blew a casket,” added the insider. “He told Carrie that she needed to choose between her career and her marriage. Mike has never held her feet to the fire like that before.”

While Underwood may be planning to have a baby naturally, an insider also claims that the couple of several years is also considering adoption. “Although the couple will be trying to conceive naturally, they’re also open to adopting,” reads the report. “Mike doesn’t care how a baby comes to them. All he cares about is that they become parents soon,” added a source.

In March, OK! Magazine reported that Underwood was in a “baby battle” with Fisher over their inability to agree on the right time to start a family. According to the tabloid’s report, Fisher allegedly gave his better half an “ultimatum” to which she allegedly agreed to attempt to conceive by the year’s end.

According to previous reports, the couple, who wed in 2010 after three years of dating, first battled over pregnancy plans following Underwood’s lead role in NBC's live performance of “The Sound of Music.” Star Magazine reported in January that Underwood had caused a rift after reneging on her promise to try for a child following the TV special’s premiere in favor of pursing other acting opportunities. “She and Mike are barely speaking,” an insider told the magazine.

Underwood last made a public appearance with Fisher at the 2014 Billboard Music Awards at the MGM Grand Garden Arena in Las Vegas Sunday. Despite rumors of marital discord, Underwood thanked her beau after winning the Milestone Award, calling Fisher her “gorgeous husband” during her acceptance speech.
