"In the earlier pictures of Zac, you can see some faint static lines on his forehead. In the recent pictures, these are nowhere to be seen and I think it would be fair to say that this is most likely due to some recent Botox treatment. His forehead is also looking very tight and taught, which are also classic telltale signs of Botox use," Transform's Clinical Director, Mark Norfolk, previously revealed to Celebs Now, though it is unclear if the establishment has ever treated the Neighbors star.

Since Zac first stepped onto the scene in his High School Musical days, the actor has gone on to star in romantic movies such as Charlie St. Cloud and The Lucky One, but has also appeared in more lighthearted films such as 17 Again, The Lorax, and Mike and Dave Need Wedding Dates.

In Touch previously reported that he is even slated to play serial killer Ted Bundy in Extremely Wicked, Shockingly Evil and Vile.
