Austin Green, husband to Megan Fox has promised to 'punch Shia LaBeouf's lights out' after the Transformers star claimed he and the Fox had an on-set fling before she married Green.
'He finds Shia cocky and irritating. The fact that he's bragged about having a thing with Megan is so tacky and insulting for Brian.' an insider told Now Magazine.
I don't see what the big deal is. Looking at the definition of the word 'fling' it means 'To throw oneself into an activity with abandon and energy. Now I don't know if Austin has seen the Transformers films, but there is constant action happening so of course there was a fling. They were probably flinging every day! It wouldn't be an action film if they weren't flung about!
