The Celebrity Big Brother star, 19, married the Green Mile actor two years ago - despite an age gap of nearly 40 years - but the pair are now said to be going their separate ways.
According to the Mirror, cracks started to appear while Courtney was in the UK after her appearance on CBB.
A source tells the newspaper: "Doug is absolutely devastated. Heartbroken in fact.
"She was not happy and wanted out."
The surgically-enhanced blonde met Doug, now 53, when she signed up for an acting workshop over the internet which he ran.
They wed in Las Vegas after a whirlwind romance in May 2011 when she was just 16 years old.
The marriage caused a scandal in the States, with Doug even receiving death threats.
