One of Tween Hollywood’s most enduring and endearing couples have called it quits after four years of dating.

Zac Efron and Vanessa Hudgens are kaput….

The love affair that was Zanessa ended earlier this month, according to various news outlets. Zac, 23, and 22-year-old Vanessa were a couple both onscreen and off and began dating while co-starring as Troy and Gabriella in Disney’s hit High School Musical franchise in 2005. The relationship even survived Vanessa’s humiliating nude photo leak two years later and the longtime couple began living together earlier this year.

Time, not infidelity, led to the split, insiders say. Tipsters ensure PEOPLE that the breakup was amicable and Zac and Vanessa remain close friends.

“”There’s no third party involved. They were together for so long. It just ran its course. … There’s no drama. No one cheated. They just grew up,” a source tells E! News.
