The 'Come & Get It' hitmaker, who sought treatment in rehab in January, and the 'Keeping Up with the Kardashians' stars were joined by a big group of friends to the first day of the annual music festival in Indio, California, reported E!Online.
The famous trio coordinated their outfits for the occasion and wore matching denim shorts, flowing tops, boots and sunglasses at the polo grounds.
"They sat in the VIP area very briefly, before it was very full, and quickly moved," a source said.
The brunette beauties were also spotted hanging out together at Sean 'Diddy' Combs' son Christian's 16th birthday at 1Oak nightclub earlier last week.
