The celebrity stylist – who teamed up with Santa Maria Novella at the 2nd Annual Day of Shopping and Fun event in West Hollywood – bought her son so many items of Jenni Kayne clothing, an onlooker tells PEOPLE. "She also told Jenni that she wants to create her own baby line."
Guests at the daytime fete, which also included Elizabeth Berkley and Johnny Knoxville, had the opportunity to get custom face paintings, eat popsicles and sip all-natural health drinks from Pressed Juicery.
"The event had a really relaxing vibe," the source says. "It was really intimate, but there was also enough for the kids to do."
