Kailyn Lowry may have her hands full with a pregnancy and two children, but that isn't stopping the "Teen Mom 2" star from writing a new book. Following the release of her 2016 publication, "Hustle & Heart," Lowry has taken to Twitter to confirm that she will soon reveal details about the moments that led up to her decision to conceive her third child.

“I have already signed a contract for it!” she told fans earlier this week.

“It’s something many wouldn’t expect and not like her previous books," a source added to Radar Online of the upcoming publication. "It’s definitely relatable.”

Kailyn Lowry will welcome baby no. 3 this summer

Kailyn Lowry announced on February 23 that she is currently expecting her third child but chose to keep the identity of the child's father a secret. The reality star is already mom to 7-year-old Isaac, from her previous relationship with Jo Rivera, and to 3-year-old Lincoln, from her marriage to Javi Marroquin.

After sharing her baby news on her blog, Lowry visited Los Angeles for a taping of the live "Teen Mom 2" after show and during filming, she was asked about her baby's father by host Nessa Diab.

However, while Lowry agreed to share details of her life when she signed up to star on the reality series, she has refused to identify the man who fathered her child and her rep informed Radar Online that she was unaware of how involved he would be in their baby's life.
