Jenna Bush calls her dad - US President George W Bush - on a The Ellen DeGeneres Show

This is the moment Jenna Bush calls her dad - US President George W Bush - on a TV chat show.

First daughter Jenna, 26, appeared on The Ellen DeGeneres Show and was asked how hard it would be to call her parents.

Writer and schoolteacher Jenna told presenter DeGeneres it was easy - and proceeded to pick up the phone and dial them to prove the point.

In the episode, which was taped on Tuesday and was due to be shown today/yesterday (wed), she can be heard first speaking to her mother, Laura Bush.

She can then be heard telling her father, George W Bush: "This is the Ellen Degeneres Show."

President Bush replies: "Well, that's great!"

DeGeneres then asks him: "How's it going?"

President Bush replies: "It's going great, Ellen. How's my little girl doing?"

DeGeneres said: "Oh, she's great. "She's scared she's going to get in trouble, because I just said, 'Is it easy to just pick up the phone and call your dad anytime?'

"She said, 'Yes.'

"So I said, 'Okay well, let's call him, and then she goes, 'Oh', and now she's scared that she's not going to get any Christmas presents."

Jenna says: "Dad?"

President Bush replies: "Yes, baby?"

Jenna asks: "Are you mad?"

President Bush replies: "no, not at all. I'm excited to talk to you. I'm glad to talk to Ellen."

DeGeneres said: "Look, we are showing a picture of you holding your daughters when they were just born. That's beautiful."

She adds: 'Alright, well, we just wanted to say Merry Christmas, and we thought you'd want to say Merry Christmas to our audience."

President Bush said: "I do want to say Merry Christmas to your audience, and I want to tell my little girl I love her."

Jenna said: "I love you too, Dad."
