The 32-year-old actress, who welcomed her first child with fiance Dax Shepard, said that motherhood has exceeded all of her expectations, reported Us magazine.
"It's actually better than I expected. It's pretty wonderful. Dax is the best dad. It's like he's just made a new best friend. He just talks to her all the time. And sings to her all day. It's wonderful," she said.
Bell also confessed that she and Dax are reluctant to share any photographs of Lincoln because they do not want her to become a public figure.
