Told you so! Newly wed Cameron Diaz has baby fever – and sources said she wants to experience pregnancy with her sister-in-law, Nicole Richie!

As The National ENQUIRER was first to report, the “Charlie’s Angels” star recently said “yes” to rocker Benji Madden, who’s the twin brother of Nicole’s hubby, Joel.

Nicole played matchmaker for Cameron, 42, and Benji, 35 – and the bond between the two A-list ladies couldn’t be tighter, insiders told The ENQUIRER.

“Cameron loves the idea of having a baby at the same time as Nicole,” said a source.

“She thinks it would be fun to go through such a life-changing experience with a close friend.”

“They can shop for baby clothes and accessories together, do pre-natal yoga and chart out their post-baby weight loss plans as a team.” But while the “Bad Teacher” beauty dreams about making babies, Nicole’s been struggling with marital woes. Joel has also been pressuring a reluctant Nicole to add to their brood of two children. 

They’re parents of seven-year-old daughter, Harlow, and five-year-old son, Sparrow. But insiders said Cameron’s enthusiasm seems to be rubbing off on her pal. “Nicole had been putting off having another child because she felt too overwhelmed with work,” a friend says. “A joint pregnancy with Cameron actually seems fun and manageable to her,” the source said.

Meanwhile, friends said Cameron’s enjoying the time she and Benji spend with Nicole and Joel.

The insider said: “Cameron thinks Benji would make a fantastic dad, and she can’t wait to finally build one big happy family with him, his brother and her best pal, Nicole!”
