Miranda Lambert is one hardworking gal, and her focus on career was what eventually led to the divorce, according to the rumors. Meanwhile, the country singer and new girlfriend, "The Voice" coach Gwen Stefani, are reportedly planning a duet.

According to Us Weekly, per Hollywood Life, Blake Shelton and Miranda Lambert agreed on a plan to have a baby, but she didn't push through.

A source also told Hollywood Life that Blake Shelton and Gwen Stefani managed to find comfort in each other.

"They have both been through horrible marriages and are bonding over that," the source claimed. "The relationship is very new, but it's a lot of fun."

Radar Online alleged that Miranda Lambert is plotting revenge as she's planning to have a baby after the divorce with Blake Shelton.

In fact, the article claimed that it was the other way around. It was Blake Shelton who didn't want children.

"Miranda's aching to be a mom and it was Blake's refusal that ultimately tore them apart," the source claimed. "Now she's her own master, and she's inspired by Charlize Theron and Sandra Bullock in a big way."

The insider continued, "Miranda's not ruling out finding a donor, but she knows it can take years so she wants to have all options available and the sooner the better."

Meanwhile, according to Celebrity Dirty Laundry, Miranda Lambert was livid after hearing about Gwen Stefani and Blake Shelton recording a duet right after going public on their relationship.

"Miranda Lambert can't believe the two 'The Voice' coaches are boldly recording music together so fast. There have been rumors that Blake and Gwen are working on their masterpiece together and it looks pretty undeniable after a Gwen sighting at Blake's studio in Los Angeles on Wednesday, November 18," it said.

Miranda Lambert and Blake Shelton have yet to respond to the new round of rumors regarding the baby and the reason for their divorce.
