Scissor Sisters frontman JAKE SHEARS is giving British singer Heidi Range something to fret about - he's admitted he's got a huge crush on her boyfriend. Despite being in a longterm relationship of his own, the homosexual singer is smitten with the sexy Sugababe's lover DAVE BERRY, and her bandmate Keisha Buchanan reveals Range is on her guard. She says, "Jake keeps telling us how much he fancies Heidi's man. He says Dave's really cute and he talks about it all the time. "I think Heidi's a bit worried!" Despite his wandering eye, Shears recently revealed he hopes to marry partner CHRIS at British music festival Glastonbury next year (07).
