Nicole Richie praises Aguilera
Nicole Richie insists close friend Christina Aguilera is a fantastic mother and wife
Nicole Richie thinks Christina Aguilera is a "great wife".
The 'Simple Life' star befriended the 'Car Wash' singer when they gave birth to their first children, Harlow and Max, last January.
Nicole said: "Christina and I haven't known each other long but we met through mutual friends. 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!"
The 27-year-old socialite also spoke about her on/off friendship with hotel heiress Paris Hilton.
She said: "We went through a phase where we weren't speaking, but I think you can safely say that for anyone who has been friends for 25 years.
"I don't really get into fights with people, and if I ever had a falling out it has ultimately been resolved. It's part of growing up."
