The Wedding Crashers star reportedly flew in from the U.S. to surprise Hudson for Valentine's Day and the two have been staying at the posh Palazzo Versace hotel.
Fans waited for hours at the nearby Pacific Fair Cinema to catch a glimpse of Wilson, who was attending a private screening, but were shocked by his violent outburst when he was spotted with the blonde actress.
The celebrity couple allegedly walked hand-in-hand to the back door of the cinema, but leaped apart and headed for separate doors when they realized a photographer was present.
Wilson then angrily jostled and swore at the local snapper and twice shoved him out of the way as he rushed up the stairs.
Onlooker and fan Jemima O’Neill tells the Gold Coast Bulletin newspaper, "We were going to ask him for a photograph, but when we saw him trying to ram the photographer we were too scared and we couldn't even look at him! We had been waiting for nearly two hours, but he was so angry we thought there is no way we're going to ask him for a photograph now!"
