Los Angeles, Oct 6 (IANS) Actress Lea Michele has offered her support to actor Zac Efron after his rehab stint.
"Lea(Michele) called Zac (Efron) and told him, 'I'm here if you need me'. She urged him to get serious about having a 24-hour sobriety coach and to only spend time with people who care about his welfare," femalefirst.co.uk quoted a source as saying.
Michele's boyfriend, Cory Monteith had died from a drug overdose in July, this year.
"Lea must feel sad that she wasn't able to prevent Cory from relapsing. She knows Zac well and would hate to see him go down the same path," the source added.
Efron has been battling a cocaine addiction.
