Temper temper!

Shia LaBeouf totally lost his cool today when we asked him if he was having an affair with his Transformers co-star Megan Fox, as it has been reported. The actor shouted a slew of expletives before making a mad dash inside his home, and it certainly seemed to us like the behavior of a guilty man!

In case you missed it, the Fury star's close relationship with the brunette bombshell is rumored to have contributed to her split with husband Brian Austin Green.

Dish Nation reported that Fox's rekindled friendship with LaBeouf, whom she hooked up with during 2008's Transformers: Revenge of the Fallen, may have been one of the key factors behind her divorce. Sources close to LaBeouf say that the two have been talking to each other since his public meltdown in June 2014, and they've grown closer, sharing life and career advice.

“Megan started speaking to Shia about a year ago when the two of them were going through troubled times. Shia was off the rails, boozing heavily, and leaned on Megan for support,” the source said.

A Fox insider says Green was not okay with this newfound friendship. “Brian has always been wary of what Shia’s capable of,” the insider dished.

We will have to wait and see how this drama unfolds!
