Heart-throb Zac Efron was overwhelmed to find out Michael Jackson is a fan of his work - and was left "speechless" when the pop superstar called to congratulate him on his success.
The Thriller hitmaker is a big fan of Efron's High School Musical franchise and is a close friend of the films' director Kenny Ortega.
And Efron admits he was delighted when Ortega handed him his cellphone and told him that Jackson was on the line for him.
He says, "I've been wanting to talk to Michael Jackson my whole life, but as soon as Kenny handed me the phone, I was at a loss for words. I have never been so speechless.
"He said he loves High School Musical. It was motivation for us, and encouragement.
