Who is super excited to have Miley’s arm around them? And why is Liam Hemsworth‘s girlfriend carrying around a mask of this guy’s face?

Find out below!

It’s none other than Jason Earles! Miley’s former show-brother!

Miley dropped in on the set of his show Kickin’ It to surprise her “little” bro for his birthday! We put “little” in quotations because dude just turned 35. He posted this pic on Twitter shortly after to show everywhere he’s close friends with the Cyrus superstar. 

We’re pretty sure Liam’s got nothing to worry about here.

Well, um, Happy Birthday Jason!
