Alicia Keys's son ready to be a big brother

Pregnant singer Alicia Keys's four-year-old son Egypt is "so ready" to be a big brother.

The 33-year-old, who is feeling very energetic despite being in the third trimester of her pregnancy, and husband Swizz Beatz are set to welcome their second child into the world on New Year's Eve.

Meanwhile, Egypt is all prepared for the new addition to the family, reports eonline.com

"(He's) so ready. Are you kidding? He's not going to be the baby anymore. He's ready," Beatz said.

"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," said the proud father.

Meanwhile, the "Girl on Fire" hitmaker is all energised.

"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," said Keys.
