The young actor had been dating his High School Musical co-star, Hudgens, since they began playing Troy and Gabriella in the popular film.
A source recently told Star magazine that last month, the two decided to take separate paths, and that now Efron is dating his Hairspray co-star, Nikki Blonsky. The source said, "Zac is completely taken with Nikki. He said she’s someone special – someone unlike any other girl he’s ever dated. He goes on and on about how funny, smart, and pretty Nikki is."
The source added, "Zac said they’ve made out and that Nikki’s a great kisser. He also thinks she’s very sexy and admits he doesn’t even notice she’s carrying a few extra pounds."
