Spotted! Liam Hemsworth was spotted getting "very cozy" with a hot blonde at a Hollywood party last week, report Radar. Uh-oh, looks like the future Mrs. Hemsworth will go cray-cray if this story is really true. For sure there's going to a big *ss drama if the rumors are true

Even though the Aussie actor Liam Hemsworth put a Neil Lane engagement ring on Cyrus' finger last June, it looks like that he is not that ready to go steady. Last October 25, the 22-year-old Aussie actor Liam Hemsworth attended the Samsung Galaxy Note II at a private home in Beverly Hills without his 19-year-old fiance, Cyrus.

An eyewitness said that Hemsworth arrived early at the tech-savy party and stayed until the end. The actor had spent the majority of the night chatting up a beautiful blonde woman in the back tent that wasn't Miley.

 "Liam was in the corner of the back tent with a blonde and they were getting very cozy, it definitely looked like they were behaving in a way that was more than just friendly," said the supposed source.

"His friend/handler was trying to keep people away and allow Liam and his 'friend' some privacy, but Liam didn't seem to be that worried about it."

Cyrus did not accompany her fiancé to the party because she was busy laying down a track in the recording studio with Pharell Williams. Before this alleged incident happened, Hemsworth and Cyrus were spotted out together in Los Angeles getting coffee.

Hemsworth is also getting busy. The actor was seen jetting from LA to Atlanta, where he is currently filming the second installment of "The Hunger Games: Catching Fire."

As for them tying the knot, reports say Miley is eager to have their nuptials to Liam with three lavish bashes around the globe so they can celebrate with all their family and friends. They are planning to have their weddings in Los Angeles, her native Tennessee and another ceremony in Melbourne, Australia, where Liam is originally from.

Cyrus is now working with designers on three different wedding dresses and the weddings has a budget of $1M for their worldwide celebrations that will take place next year.
