British hunk Orlando Bloom fears he can't compete with girlfriend Kate Bosworth's latest onscreen flame - because he's no real life Superman. Bosworth, who plays Lois Lane in new movie SUPERMAN RETURNS, is seen on screen cuddling up to co-star Brandon Routh's Man Of Steel. But Pirates Of The Caribbean star is philosophical about their sizzling chemistry, and admits there's no point suffering pangs of envy. Bloom says, "Jealous? Are you kidding? He's Superman. I'm just a pirate."
