Pop star Hikaru Utada said on her official website Friday that she just gave birth to a baby boy.

"Our baby has arrived! He's a calm little boy who drinks and sleeps well," she wrote.

Utada, 32, also revealed that she was working on a new album while pregnant.

"It is going to take some more time before it's completed, but I'm eager to start working on it again. Stay tuned!" she wrote.

After ending her first marriage in 2007, Utada married Italian bartender Francesco Calianno, 24, in Italy on May 23, 2014.

In 2010, she decided to suspend her musical activities for an indefinite period from 2011 to focus on "human activities."
