After the multi-awarded country singer and the NHL star Mike Fisher welcomed their first born son Isaiah Michael Fisher in February, the first-time parents are reportedly looking forward to add another member to their family.

Recent rumors claim that the couple wants to have another child as soon as possible and that they want Isaiah to have a baby brother or baby sister close to his age.

Their desire to have another child shortly after their first one might come as a surprise since they took their time before having Isaiah after they got married in 2010. A year before they announced the pregnancy via Instagram, Underwood claimed that she did not feel old enough to have a child. "I know I am mature. But being responsible for another human?" Underwood told Marie Claire.

But after learning about the joys of having a child, a source told Life & Style that the two want to have another one soon. "She'd like to become pregnant before the tour starts. Some of her pals have told her that's a crazy idea, but Carrie's up for a challenge, and she's got the resolve of an Olympic athlete," the source said.

This means that the 30-year-old singer wants to get pregnant before her "Storyteller Tour: Stories in the Round" tour kicks off in Jan. 30.

However, Underwood earlier told Belfast Telegraph that though she and her husband want to expand their family, they have no intention of doing it anytime soon. According to her, bringing a child to a nationwide tour needs a lot of adjustment on her part.

"I'm still figuring out how it will be when I take him on tour with me next year and when I have more children," she explained. "I have to be with them; that's not negotiable. We'll probably be figuring our way through this."
