Friends of Nicole Richie have noticed some changes in the Simple Life star in the month since she announced she was seeking treatment to help her gain weight. "She has [gained] at least five pounds," says a source. "She wants to prove she's trying to change." As reported in the last few weeks, Richie has also "distanced herself from a lot of [old] friends," according to the source, including a public parting from stylist Rachel Zoe. "She's doing great," said a friend who spoke to Richie over Thanksgiving. "She's taking care of herself and is in a good place." Even former nemesis Paris Hilton is singing Richie's praises, saying, "She looks better than she's ever looked. I love it."
