Guess Who Just Joined Twitter?

Welcome to the land of 140 characters or less, Liam Hemsworth!

"The Hunger Games" star just joined Twitter, but don't get your hopes up for any personal revelations. Judging by who he follows, the 23-year-old actor is going to be all business on the social networking site.

Hemsworth, 23, is following his films "Paranoia" and "Catching Fire." In fact, he has yet to follow his fiancée Miley Cyrus! But don't let that fuel start rumors just yet … Hemsworth has only posted once and that was a few hours ago.

He tweeted: "Kicking it off on Twitter for the first time. Glad to be on board. Thank you for following... -L"

While it's not unusual for a celebrity to join Twitter purely for promotional purposes, it is a tad ironic since Hemsworth urged Cyrus, 20, to quit the social networking site when they first started dating.

“FYI Liam [Hemsworth] doesn’t have a twitter and he wants ME to delete mine with good reason,” Cyrus tweeted in October 2009. The then-16-year-old went on to make a rap video to explain why she really quit.

Take a trip down memory lane and check it out below, then peek at the "Paranoia" trailer.
