Nicole Richie Says Christina Aguilera Is A Great Mom

Nicole and her boyfriend Joel Madden recently announced the happy news that they are expecting their second child.

The former Simple Life star chats about her fellow famous mom Christina Aguilera. The two have become fast friends after the birth of their kids last year - Nicole’s daughter Harlow was born just one day before Christina’s son Max.

“Christina and I haven't known each other long but we met through mutual friends," Nicole says. "Because we had our babies at the same time - they were born one day apart - we've got to know each other. She's a great wife, great mom and great singer. She does it all. And I'm sure Max gets better lullabies than Harlow!"

Earlier this week the busy mom put in an appearance at Kitson in LA for the launch of her House of Harlow jewelry line.
