Zac Efron's doll has made him blush. The teen heartthrob has admitted he had been so amazed at how his "Hairspray" doll looks so much like him that he couldn't help but blush.

The 20-year-old star says, "The first time I saw my doll for the movie 'Hairspray,' it totally made me blush! Surprisingly, it looks a lot like me. I was very pleasantly surprised. But I still find it really strange that people want to collect them."

Efron says that although he wants to be arrogant and conceited of the fame he has, he remains modest because of the people around him.

He tells Top of the Pops, "If I ever gave the slightest hint of having a big head, I'd be chopped down so quick by family and friends."

"I'd love to be cocky, wear sunglasses and drink ice-blended coffee every day, but I have too many people pulling me back."
