Legolas and Arwen sitting in a large meandering tree, k-i-s-s-i-n-g. And maybe talking a bit dirty in Elvish.

The pair - who obviously worked together on the Lord of the Rings trilogy - were supposedly spotted getting cosy in New York City at the opening night of Broadway play Waiting for Godot, starring Patrick Stewart and Sir Ian McKellen, before heading to the after-party at Bryant Park Grill in New York City.

A source told the new issue of America's (the highly reputable) Star magazine: "When they got behind closed doors, they were playfully tickling, gazing into each other's eyes and holding hands."

Orlando split from his wife Miranda Kerr - with whom he has two-year-old son Flynn with - in October and he is allegedly trying to keep the budding romance secret out of "respect" for the model. Which is fair enough given most folk reckon they're back together.

36-year-old Orlando said of his relationship with Kerr: "We're a family and we'll always love each other and we're going to be in each other's lives."

Miranda has been romantically linked to her long-time friend, Australian billionaire James Packer, in the last few weeks. James, 46, split from his wife, Erica Baxter (also a model, as it happens), three months ago.

So it's all turned out nice again.
