Last month Bloom flew to Sydney, Australia to visit Bosworth on the set of Superman Returns, where she had reportedly struck up a brief romance with director's assistant Lundi Shackleton. Sydney newspapers claimed Bosworth used her fling to reunite with Bloom.
After Bloom was photographed cuddling up to ex-lover Miller--only a week after she discovered her fiancé Jude Law had cheated on her with his children's nanny--is actress sister Samantha Bloom insists her famous brother is only in love with Bosworth.
Samantha says, "They've been together for two years and they are still very much together.
"Of course they [Sienna and Orlando] kissed--they are friends and he always kisses his friends."
