Jazmin Cullen, 24, from Surrey, married Jason Cullen months after meeting him, the couple went to stay with her grandmother in Brighton for honeymoon.
Her grandmother found indecent images on her laptop which Cullen had used.
She then found out that Cullen, 31, a former ambulance call operator, had also lied to her about his identity and criminal past.
Two years earlier he had been jailed for possessing 8,000 child abuse images, including some graded the worst possible, and exchanging them with fellow paedophiles.
He had served half of a two-year prison sentence and met Jazmin shortly after being released.
But she knew nothing of his sickening secret until her grandmother found the disgusting child images on her laptop and realised Cullen had downloaded them.
The pair reported Cullen – whose real name is Jason Hodson – and he was hauled back to court and given a community order.
She said: ‘If it wasn’t for the fact that his pictures were in articles I found online, I would never have believed he had this double life. I was completely dumbfounded.’
Cullen pleaded guilty to possessing the 20 indecent images found on his grandmother-in-law’s laptop at Sutton Magistrates’ Court in April 2011.
The court heard he had allegedly been abused aged 16, but no one was ever arrested, charged or prosecuted.
After the hearing, having already spent 14 weeks in custody since his arrest, he was given an 18-month community order and fined £85.
‘Seeing him convicted was a mix of relief, complete devastation and disbelief,’ Jazmin said.
‘I did love him completely, and my wedding day was a lovely and happy day for me at the time, but now thinking of him is very distressing.
‘Divorcing him will be the final step in moving on but so far he has denied me that.’
