On the Apr. 27 Hills premiere, Kristin Cavallari strongly dismissed her costars' insinuations that she has been doing drugs, but sources tell the new Us Weekly (on newsstands now) that the MTV reality star, 23, is spiraling out of control.
Earlier this month, after a night of drinking at the All Points Worldwide Night Visions Oasis party at Coachella in Indio, Calif., Cavallari, 23, joined 37-year-old actor Jason Statham and several others for a late-night spin in a golf cart, the new Us Weekly reports. "They got pulled over by the cops and were told to go home," recounts a Cavallari acquaintance, who tells Us Weekly that throughout the music festival weekend, the star "was drinking and partying. I saw her do a line of cocaine."
Though Cavallari's lawyer denies she uses drugs, a source tells Us Weekly: "The dudes she hangs out with are all party promoters — and they’re party animals."
Adds another: "She's been sucked into the Hollywood scene. She's surrounded by the leeches who enable her."
