Nicole’s longtime BFF, Paris Hilton, 28, may be joining the mom club now that she’s serious with The Hills’ Doug Reinhardt. “Paris would make a great mom — she’s my Angel Princess. I’d love to have some mini Parises one day,” Doug told In Touch at LA’s MyHouse on March 20. “I’d love to have children, that’s what completes your life,” added Paris. Doug, 23, is also a better fit than her ex Benji Madden. “She thought she could look past his tattoos and piercings, but Paris wants her children to have a clean-cut father,” says an insider. “And they’re crazy about each other.”
