played good friend on Thursday – shopping for baby gifts for her pregnant pal Nicole Richie
Hilton headed to the hot Hollywood boutique Intuition, perused the baby section and walked out with a dozen bags of merchandise full of goodies for the baby Richie is expecting with Joel Madden.
"She was in the best mood," a source tells PEOPLE. "She couldn't wait to get to the baby department and look for things for Nicole's baby. She said she was very happy for her."
Hilton was an equal-opportunity shopper, choosing gifts in both pink and blue. Among the items she bought was a Tuni & G Baby set (pants and T-shirt) with the text "Don't Ya Wish Your Mommy Was Hot Like Mine" with the pants bottom saying "Don't Ya." She also bought Baby's First Fashion Words
book, a Baby Jar Baby Snuggler Blanket and Trumpette socks.
"She can't wait to hang out with the baby," says the source about Hilton. "She's happy Nicole is healthy and thinks she looks great."
Hilton, 26, told PEOPLE
last week about Richie: "I know she's going to be the best mom ever."
In a series of interviews on ABC at the beginning of the month, Richie, 25, told Diane Sawyer that she is four months pregnant
with musician-boyfriend Madden, 28.
