Christina Aguilera and Nicole Richie to team up for movie?!

Christina Aguilera is planning to make another movie — and she wants her costar to be her BFF Nicole Richie! The singer-actress — who can soon be seen starring alongside Cher in upcoming flick Burlesque –  is apparently ready to sign up for a comedy surrounding two showbiz mothers and wants friend and fellow real life celeb parent Nicole to join the cast.

“Christina is very excited about this move into acting,” a source said.

“As a mother she’s particularly keen on a comedy role in which she gets to play one of two diva mothers in Hollywood. She wants Nicole as the other half of the double act. They are already a great double act as friends and parents.”

Meanwhile, Aguilera says she has increased respect for single mothers since she split from husband Jordan Bratman.

The 29-year-old pop star — who has a two-year-old son Max with the music executive — now realizes how tough it is to care for a child alone since she separated from Jordan in October.

“My focus first and foremost is my son Max. More power to single moms and those out there doing it,” she said.

“At the end of the day, he’s the love of my life. I adore him and he’s such a character and he’s so happy and that’s what’s most important.”
