"We're so excited that our daughter Evie is going to get a baby sister or brother for Christmas," says Dierks in the PEOPLE exclusive posted online today.
Dierks said their toddler Evie is looking forward to having a new baby brother or sister. "She's pretty obsessed with a baby doll she carries around now ... We'll see how she does with the real thing!" Bentley says.
No word on how Jake and George, the Bentley family dogs, feel about the new family member. He told talk show host Bonnie Hunt that the boys are very protective of Evie.
"They were very patient," Dierks says of his beloved dogs, adding that they have been very accepting of Evie despite understandable concerns from him and his wife, Cassidy. "Jake thinks his job is to protect me from squirrels," the proud dad explains. "And he thought kids were big squirrels."
It didn't take Jake long to understand that Evie was a member of the family and also someone to be protected, The Boot reported last year. "He's been great, ever since she came along," Bentley praised his pet. "I brought the blanket home [from the hospital] and [let him] sniff it before she arrived. He's funny, we'll go to check on Evie and we'll look into the crib and there's Jake, right there with us. He wants to check on her, too."
