“She's a doll," McEntire gushed about baby River. "She's been in London with her mom and dad and her granddad because my husband manages myself and Kelly. So they've been very busy and that's given a lot of together time for Narvel and River. And he's loving every minute of it. He sends me videos and pictures every day.”
McEntire doesn't hesitate to defend her daughter-in-law, who has faced harsh criticism over her weight and recently admitted that she has struggled to find artists to collaborate with, but she doesn't think Clarkson needs any help fighting her battles.
"You know Kelly's a big girl," McEntire told ET. "She's always been able to defend herself and take up for herself. But if there's any slack needed to be taken up, I'll be there for her in a heartbeat."
The 59-year-old performer was "thrilled to death" when Clarkson married Blackstock in 2013, and she couldn't be happier for the positive developments in her daughter-in-law's life, both personally and professionally.
"I'm very proud of her," said McEntire. "She's a girl with a big heart. Very giving, loving, and talented. Everybody knows she's talented but sometimes they don’t see that big-hearted loving person that she really is. And I'm so happy for her, I've never seen her happier than she is right now."
