JAKE GYLLENHAAL - GYLLENHAAL'S STRUGGLE WITH GAY PLOT

Actor JAKE GYLLENHAAL admits he's terrified of his upcoming onscreen gay kiss with HEATH LEDGER, because he has no idea how to fake homosexual intimacy.

The hunky star is teaming up with Ledger in BROKEBACK MOUNTAIN but is struggling to cope with the demands of the storyline - and even his girlfriend KIRSTEN DUNST has failed to lift his spirits as the steamy scenes approach.

He says, "Kirsten looked at the script and said, 'Well, you aren't gay and neither is Heath, so there's a lot of acting required.'

"I just can't come to terms with it. I know what we have to do and it's very intimate. I'm blanking it out until we have to do the filming. I've spoken to Heath and he sounds terrified."
