Christina Aguilera has gotten pretty chummy with Nicole Richie since the two blondes became media mothers only a day apart last January.
"I didn't know much about Nicole," Aguilera told press after an AMA party.
"I've had the opportunity of getting to know her and I was blown away with how great of a mom she is.
"I actually ask her for advice because she has a lot of great things that she does for her little one," Aguilera continued.
"Having a child has made her grow so much as it has made me grow," Aguilera added.
"I have nothing but good things to say about Nicole... She's a great woman."
