Paris Hilton and Nicole Richie are best friends and they will always share the same feeling with each other. The laugh, the tears and everything. And days after Nicole came out with her public revelation on her being pregnant, Paris speaks out on her BFF's impending motherhood.

"She's really happy," the hotel heiress told People. "I just got off the phone with her. She's so excited. I know she's going to be the best mom ever."

Nicole sent shock to public worldwide with her revelation that she's nearly four months pregnant with boyfriend Joel Madden's child, telling ABC News' Diane Sawyer for an interview aired earlier this month, "Yes, I am. We are. I'm almost four months."

She, moreover, also dismissed the persistent eating disorder rumors, insisted "No, I do not have an eating disorder. I've never had an eating disorder, ever. It's anxiety, it's stress, it's just, it's just not being careful." She, on the other hand, is willing to gain as much weight for the sake of her unborn child. "I eat all the time, especially now. I'm constantly hungry. I'm eating at least every hour," she said. "And just like any mother, you want to take the best care of yourself, especially while you're pregnant. I'm definitely eating healthier now."
