The actor gets naughty with Anna Paquin
The hot 29-year-old wears nothing but an unbuttoned black shirt and a necklace to fool around with American star Anna Paquin in woodland.
His bare chest is covered in splashes of blood, while Anna, 30, has red goo dripping down her chin.
In the scene, Rob‘s half vampire-half faerie character Macklyn Warlow warns Anna‘s alter ego Sookie Stackhouse that he may not be able to control the vampire inside him when night falls.
Sookie ties Macklyn‘s hands to a gravestone but later realises she can’t resist the bloodsucker and lets him feed on her before they get frisky on the grubby floor.
It’s not just Rob who shows off his fit abs on the US show – naked Anna reveals her impressively flat tum just months after giving birth to twins.
