Hollywood actor Orlando Bloom is NOT dating Sienna Miller and is still a couple with actress Kate Bosworth, according to the actor's sister, Samantha.

Orlando Bloom was spotted cuddling with ex-lover Sienna Miller, just one week after Sienna's fiancée, Jude Law announced public that he cheated on her with his children's nanny, Daisy Wright and apologized to her.

IMDb quotes sister Samantha as saying: "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."

The actor has previously been linked to actress Christina Ricci and supermodel Sophie Dahl. Orlando and Kate met at the shooting of an advert for clothing store Gap, in 2003.
