A woman has divided the internet after revealing that she's now dating her step-brother.

The woman, who is only known by her first name Maddie, met Callum when she was a child after their parents got engaged. She admitted to having a crush on him for years, Indy100 reports.

However, their parents' relationship broke down a number of years ago and the wedding was called off.

Maddie and Callum never saw each other again and were only nine years old at the time.

But the pair were recently reunited on the popular British ITV2 show, Secret Crush.

On the show, it was revealed that the pair had kept in touch on social media, and it was through this virtual connection that Maddie developed a crush on Callum.

She decided to see if the feelings were mutual on the dating show.

Maddie said at the beginning of the episode: "I'm here to tell my brother that I fancy him. Just to be clear, we are not related - my mum and his dad were together many years ago.

"But since we got back in touch on social media he's really matured and he's very good-looking."

She explained that she thought there might be a connection between her and Callum when they got "flirty" on social media.

Maddie added: "I feel quite nervous about telling him but I'm also quite excited because I'd be interested to see what he thinks and what he has to say. If this goes badly I think we can say goodbye to any future family reunions, but hey ho."

Prior to going on the show, Callum had absolutely no idea that Maddie had feelings for him.

Callum was understandably shocked when his step-sister turned out to be his secret crush.

Blushing, he said: "I can’t believe it's you. That's mad, that's crazy. You were the last person I expected to walk through that door.

"I (haven't) seen you in years, we haven’t even spoken that much - you've kept it a right secret. I'm blown away, to be honest."

Maddie opened up about her long-term crush as the pair shared a drink.

"You're just sound and genuine. You've really matured since I last saw you and I was like yeah, I want to meet you," she said.

The pair then addressed whether or not their relationship would be legal.

Maddie said: "I don't think we're breaking the law. Unless we're secretly related."

Callum replied: "Basically we were not even stepbrother and sister because (our parents) didn't get married."

Needless to say, the episode went down a storm on social media.

One Twitter user wrote alongside a sick emoji: "So you fancy your ex step-brother. #SecretCrush"

However, a third Twitter user was less critical and simply wanted to see what would happen for herself.

"#secretcrush #itv2 'I'm here to tell my step-brother I fancy him' Now I have to watch it," they wrote.
