Orlando Bloom is still dating Kate Bosworth and is only "friends" with Sienna Miller, his sister has revealed.
The 28-year-old Lord Of The Rings star was spotted having a smooch with Jude Law's estranged fiancee this week... but it is all perfectly innocent, so we're told.
Orlando was photographed cuddling up to Sienna - who he previously dated - only a week after she discovered Jude had cheated on her with his children's nanny.
But his sister Samantha insisted her brother is only in love with Kate.
She said: "They've been together for two years and they are still very much together.
"Of course Sienna and Orlando kissed - they are friends, and he always kisses his friends."
Beyond The Sea beauty Kate said they were ending their two-year relationship in January to concentrate on their careers.
However, according to movie website imdb.com, the couple were spotted together again in March.
Last month Orlando flew to Sydney to see Kate on the set of Superman Returns, where she had reportedly struck up a brief romance with director's assistant Lundi Shackleton.
Sydney newspapers claimed Kate had ended her fling to reunite with Orlando.
