HOLLYWOOD comedian Jack Black is expected to make a guest appearance on Channel 9's Australia's Got Talent on Sunday night. 
The School Of Rock star - who will fly into the country for the premiere of his new flick Kung Fu Panda 3 the same day - will have an unknown role on AGT, though sources say he could burst into song.
Black will appear alongside judges "Dicko", Sophie Monk, Kelly Osbourne and Eddie Perfect, for the show's grand finale, which will continue on Monday night.
When Black (above) was last in Australia, in 2013 for the premiere of Kung Fu Panda 2, he weighed in on our gay marriage debate, claiming ex-PM Tony Abbott's stance on the issue was archaic."The guy is living in the Stone Ages though he's not seeing the writing on the wall," he said. "He sounds like a bit of a nutter â€¦ A nutter butter."
