New Delhi, March 9  Nicole Richie admires fellow mum Christina Aguilera for being a "great wife, great mom and great singer".

The American actress welcomed her first child Max around the same time when Christina gave birth to her little Harlow last January.

The 27-year-old showered praises on the `Beautiful' hitmaker, appreciating the skill with which she carries her multiple roles in real life, reports the China Daily.

"Christina and I haven''t known each other long but we met through mutual friends," Nicole said.

"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!" she added. (ANI)
