Lilly tells EW, that while her character will have a love story, she only hints that it could be with Legolas (Bloom):
“Tauriel’s relationship with Legolas is significant. They’ve known each other since they were children, and Legolas’ dad, [Elven king] Thranduil, has a soft spot for Tauriel and sees something very special in her. So if you grow up side by side, and your dad has a very special spot in his heart for this young woman who’s a fantastic warrior, I think it’s hard not to notice her.” She laughs. “That’s probably as much as I can say.”
I guess they’ll be adding a bit of a love story aspect with Legolas (Orlando Bloom). Kind of a shame, seeing that we never even hear of her in Lord of the Rings. It’ll be interesting to see where that goes. The Hobbit: The Desolation of Smaug is set to release on December 13th.
