Whoever said that sparks fly only for the young celebrities have been proven wrong by Alexander Skarsgard and Nicole Kidman's intense chemistry on-screen with their new series on HBO, "Big Little Lies." Skarsgard is romantically linked to it-girl, Alexa Chung, while Kidman is currently in a relationship with Keith Urban.

However, the palpable on-screen chemistry of Alexander Skarsgard and Nicole Kidman have been making the fans speculate that there might be something more outside of their characters. Are Alexander Skarsgard and Nicole Kidman dating?

Given the premise that the series they are starring deals with mature and serious issues like domestic violence, Alexander Skarsgard and Nicole Kidman are faced with intimate love scenes that require a lot of skin. According to People, the "Tarzan" actor actually went full-frontal for a scene in "Big Little Lies." Of course, the "Battleship" actor is not known to be shy and has been comfortable with showing some skin in previous projects.

Seasoned celebrities like Skarsgard and Kidman have probably experienced a lot of daring scenes to act out in their early years, so their roles in "Big Little Lies" are just considered purely professional. However, they were so effective in playing their respective roles that the fans have already begun to have a hard time drawing the line between what's real and reel, fueling Alexander Skarsgard and Nicole Kidman dating rumors.

Meanwhile, Kidman shared that while she treats all the scenes with Skarsgard professionally, there are times when she reportedly feels drained and emotionally affected when the director says "cut." It appears that Skarsgard feels somewhat the same. According to Daily News, the "True Blood" actor felt bothered and devastated when he saw the "Moulin Rouge" actress' bruises after a grueling fight scene. The Alexander Skarsgard and Nicole Kidman dating news might still be unconfirmed, but fans can be sure that the "Big Little Lies" on-screen couple are really taking their characters by heart.
