But in a rare sign of social media affection this week Cormack posted a bed party with her beau to Instagram. She channelled her acting skills in the four pictures, writing: "Happy. Sad. Angry. And s*** Ashley Hamilton hack list."
Cormack - who plays Bea Smith in the prison drama - recently explained she likes to keep her love life private these days, pointing at her pairing with Boy actor Pana Hema-Taylor, 25, with whom she had her second son.
Cormack would only say she was in a fantastic relationship now, adding she opened up in interviews too much when she got together with Hema-Taylor in 2010. Cormack and Anthony share a love of riding Harley Davidson motorbikes.
