Andrew Tate says he doesn’t recognise himself when he looks in the mirror in prison

Being locked up in prison for two months has clearly taken its toll on Andrew Tate.

The controversial former kickboxer was detained by authorities in Romanian back in late December.

Romania's Directorate for Investigating Organized Crime and Terrorism (DIICOT) is leading an investigation into whether Tate is involved in a human trafficking and organised crime group.

He's also being investigated for rape allegations.

Tate says the weeks of being inside a Romanian prison cell have been rough on him.

Taking to Twitter, he said: "I saw my reflection today and I barely recognized myself. A long beard, a full head of hair and the stresses of battle show on my face.

"But then I looked into my eyes and recognized myself completely. They cannot break me."

Tate has been fairly upfront with his followers about what life is like in jail.

He previously complained the conditions were, unsurprisingly, not great.

The 36-year-old released a newsletter to his supporters, where he said: "They're trying to break me. Thrown inside a cell without light.

"Cockroaches, lice and bed bugs, are my only friends at night.

"When the guards bring me to and from the courtroom, I stay absolutely respectful.

"They try to pour hatred into my heart. But please and thank you, you stick with me at all times.

"Our prison guards are just performing their jobs, they have families to feed in times of hardship. Do not forget your manners.

"They are trying to break my iron mind with unjust imprisonment. My absolute respect for everyone around me is my act of absolute rebellion.

"They cannot break me."

But, several weeks later he revealed he's making the most of his time inside his cell.

He bragged that he's able to walk 10 kilometres inside his small home every single day and is able to punch out 500 pushups and squats.

In addition to that, he said he practices his 'tiger paw technique', he 'writes and complete lessons for the students inside "The Real World"', and he 'reads and respond to 100s of letters'.

Tate believes it's embarrassing if people on the outside world aren't able to at least do that.

"You have all your freedom of movement. You have unlimited information and accessibility at your fingertips," he said on Twitter.

He added: "If my days in this cell are more productive than yours, you should be furious with yourself.

"It means you are failing.

"How will you ever reach greatness when you do not even outperform a man in a jail cell?"

A judge in Romania recently extended Tate's detention inside prison for another 30 days, meaning he will stay behind bars until the end of March.

It's the third time prosecutors have successfully petitioned to elongate his stay inside jail, despite no charges being filed yet.
