Alicia Keys' son is ''so ready'' to be a big brother.

The 33-year-old singer and husband Swizz Beatz are set to welcome their second child into the world on New Year's Eve (31.12.14) and says their four-year-old Egypt is very excited about their impending arrival.

She said: ''[He's] so ready. Are you kidding? He's not going to be the baby anymore. He's ready!''

Swizz added: ''He's already preparing. He has like a little doll where he's like, 'Am I supposed to be doing this? Am I supposed to be doing that?' He's so ready. It's a blessing.''

Meanwhile, the 'Girl on Fire' hitmaker is feeling very energetic despite being less than two months away from her due date.

She told E! News: ''I feel really good. My husband was just saying, he was like, 'Baby, I really need you to like get some rest,''' because I'm just invigorated. I'm just moved. I started something called the We Are Here movement, which supports Keep a Child Alive and 12 other organisations as well. And it's really about how I realised we can't solve the world's issues in isolation, we have to do it in a holistic view. So I'm just motivated. I can't help it!''
