Former Married At First Sight bride Hayley Vernon has hit back at critics who say she doesn't have a 'real job', after coming out as a high-class escort.

The 35-year-old, who is also a porn star on OnlyFans, took to Instagram on Tuesday to reveal how frustrating it is when people question the value of her career.

She said she contributes a great deal to society through her line of work, not just because she provides a service to the community, but also because she pays tax on her income.
