THEY might not be dating in real life anymore but they’re definitely taking their Big Bang Theory relationship to the next level.

The hit show’s frontrunners Kaley Cuoco and Johnny Galecki recently shot a wildly racy scene deemed ‘too hot’ by some networks.

Cuoco shared a behind-the-scenes snap of the pair wearing a bright, fitted corset she writes took “15 minutes to get on.”

Her co-star Johnny Galecki, who she is married to on the show, stands next to her with an S&M toy in hand while dressed in leather chaps with his signature glasses tucked into one of his bondage straps.

The scene is actually a nightmare Sheldon, played by Jim Parsons, has, where the couple has turned his bedroom into a sex dungeon.

It remains to be seen whether or not Nine, the Australian channel that airs the show, will include the scene.

The episode is number seven of the show’s 10th season and aired in the US on November 3. Advertisers have reportedly deemed the scene ‘too hot’ for UK screens and have banned it from the episode.

Johnny Galecki and Kaley Cuoco dated in real life for a number of years from 2008 however Cuoco now dates equestrian, Karl Cook following her failed marriage with tennis player Ryan Sweeting.

Cuoco and Galecki’s characters tied the not in the tenth season premiere and while some may cringe at the idea of working and being on-screen married to your ex, the two are good friends.
