Kelly Clarkson: "My husband is such a great father".

A heavily pregnant Kelly Clarkson has given an emotional interview about her husband Brandon Blackstock – and his incredible parenting skills.

The American Idol star, who is expecting her second child (a son) soon, is also mum to daughter River Rose.

Clarkson, 33, recently told On-Air with Ryan Seacrest that Blackstock was an incredible dad.

“He’s such a great father,” she began.

“Watching my husband love on his daughter all the time, go to her events and just be there and be present is hard to watch, but beautiful to watch. I know that my kids are going to have that.”

Clarkson also spoke about her troubled relationship with her own father.

“I don’t even think I understood the gravity of [my relationship with my father] until I was pregnant,” she said.

“I was like, ‘I cannot imagine not seeing this kid to his or her full potential and just seeing what she’s going to do, what she’s going to be like.’ ”

All the best with the rest of the pregnancy, Kelly - and we're sure you and your husband will continue to be wonderful parents to baby number two.
