10 Things You Need to Know About Zac Efron
2. Another big event for Zac in fifth grade? His first kiss! It turns out, Zac had his first kiss in fifth grade during a game of Truth or Dare! Zac told Seventeen, "It was in a tree fort. It was over a game of Truth or Dare, but turned into 'make out with the other person.' I was, like, the only boy and there was a bunch of girls. I was pretty stoked." LOL! Zac's now rumored to be kissing (and dating) his Neighbors co-star Halston Sage. Take a look at this photo of the pair filming a scene for the movie!
