New Delhi, Dec 11 : Pop star Ashlee Simpson, who recently gave birth to her first child, says motherhood is the most fantastic experience.

The `Never Dream Alone' hitmaker revealed that her baby Bronx Mowgli is the best part of her day, as he makes her laugh and smile at the same time, reports China Daily.

"Motherhood is the most fantastic experience I have ever been thru. Bronx makes me laugh and smile every day," Ashlee wrote on her MySpace Celebrity Blog.

Although Simpson gave birth to Bronx on November 20, 2008, she has already been on few outings.

"I finally left the house for Fall Out Boy's show on Monday night, which was so good," she wrote, complimenting husband Pete Wentz's band's new material.

"Their new songs sound awesome live, I can't wait for their new record!" she added. (ANI)
