Jana Kramer is pregnant with her second child after experiencing multiple miscarriages.
"I'm so excited," she told the magazine.
"We lost in October and then we did an IVF cycle and we lost in February, so I want to be able to be like, 'Hey, I know it's hard but just try to have some hope.'"
Kramer married Caussin in May 2015, and is parent to 2-year-old daughter Jolie Rae with the former tight end. The couple separated in August 2016 but later reconciled.
"Surprise! We have a rainbow baby on the way & couldn't be more excited!" the star wrote. "Jolie is going to be a big sister & we're becoming a family of 4!"
Kramer told Us Weekly in May that she had experienced several miscarriages in her attempt to have a second child.
Kramer is known for playing Alex Dupre on The WB/CW series "One Tree Hill," and has since appeared on the ABC reality competition "Dancing with the Stars."
She released the album Thirty One in October 2015.
