CALIFORNIA: Liam Hemsworth has joined Twitter. The ‘Hunger Game’ actor has set up his own verified account on the micro-blogging site but has only posted one tweet so far. He wrote: ‘’Kicking it off on Twitter for the first time. Glad to be on board. Thank you for following.’’ While Liam quickly racked up over 20,000 followers on his first day, he is only following five accounts, none of which belong to his on/off fiancee, prolific tweeter Miley Cyrus. Meanwhile, troubled Amanda Bynes shared her admiration for the 23-year-old actor, writing on Twitter that she thinks he is ‘’gorgeous’’.–ES
