Speaking to WHO, body language expert Blanca Clobb said Cody is "enjoying the moment" and Miley is proving she "doesn't care about comments or criticism".
She added that many of the couple's photos were just for "shock value" rather than showing their relationship as a great romance.
“Miley’s hand down the front of Cody’s pants is all about shock value to the world and a secret message between the two of them," Blanca said, referring to a recent Instagram photo showing the shirtless 'iYiYi' singer posing while Miley's hand was touching his crotch.
The expert's comments come after it was reported that Miley has been using her relationship with Cody in an attempt to make her ex-husband, Liam Hemsworth, jealous.
Multiple insiders have confirmed the pop sensation is still doing everything she can to make Liam jealous and get under his skin.
“She was drunk dialling him for a while, so now she’s resorted to social media to get his attention,” a source told Radar Online.
They added Miley is desperately trying to prove she's moved on, however, is still struggling to cope with the breakdown of their marriage.
