The king and queen of "High School Musical" are going their separate ways.
"It was mutual," the source explains. "They have been together for so long. It just ran its course."
And, the insider insists, "They are still talking and still friends. There's no drama. No one cheated. They just grew up."
Efron, 23, and Hudgens, 21, met in 2005 while making the first "High School Musical" flick, and became a romantic item about two years later.
"Right off the bat, we had a connection," Hudgens told Glamour magazine earlier this year. "I think everybody could see it. When we had our audition, they paired us together. And he was adorable."
"I think that we inspire each other," she added. "[I love] having someone to grow with."
Efron admitted to Details' September issue that he had pondered the single life. "Everyone tells me [to play the field]," he said. "I think a lot of guys would enjoy that. But I'm not really like that."
He shot down claims that their romance was an elaborate publicity stunt. "That's just f***ing insane... . It would have been so much easier to call it off a long time ago."
