Music mogul Clive Davis was so upset by pal Whitney Houston's decline into a drug hell, he called on rocker Courtney Love to mentor the troubled soul star, according to US reports. Love, who has gone through her own drug abuse problems and now insists she's clean and sober, jumped at the chance to help another struggling star and agreed to stage an intervention with Davis. According to the new issue of America's Us Weekly magazine, Love and Houston have become unlikely friends and former Hole star Love has turned Houston onto her own addiction counselor Warren Boyd. The publication claims Davis, who discovered Houston, is paying for her expensive counseling sessions.
