One of YouTube's most popular gaming personalities has been accused of infidelity and emotional abuse by his estranged wife, just hours after their split was made public.

In a series of tweets shared Thursday, Heidi O'Ferrall blasted her soon-to-be ex spouse, Jared Knabenbauer, who boasts 1.3 million subscribers on his ProJared YouTube channels.

O'Ferrall accused Knabenbauer of 'gaslighting' her and of conducting a lengthy affair with popular artist, Holly Conrad.

'I recently learned that my husband @ProJared has been f**king @HollyConrad behind my back for months!' she wrote on Twitter.

'I have proof. Explicit conversations and photographs of their relationship, which he extensively lied to me about on many occasions.'

She later tweeted to Conrad directly, stating: 'Honestly @HollyConrad you look very ashamed and insecure in all the nudes you sent my husband.

'I think it would help your chronic self esteem issues if you started f**king men that weren't already married.'

O'Ferrall continued hitting out at her estranged husband, and then accuses him of soliciting explicit images from fans.

The drama began on Thursday evening, when Knabenbauer announced the end of his marriage to O'Ferrall in a statement shared on Twitter.

'My wife Heidi and I have filed for divorce. I know this may come as surprising and upsetting for many of you, but know that we do this so that we may both seek happiness for ourselves,' he wrote.

Appearing to anticipate accusations of infidelity, Knabenbauer then added: 'During this time you may see a lot of rumors, speculation and gossip going around. I ask that you make your own observations and come to your own conclusions.'

Hours later, O'Ferrall took to Twitter claiming she was blindsided by the split announcement, and claimed that it was an attempt 'to silence her'.

'I gave him the opportunity to make a statement about his infidelity before I did. I told him it would be less embarrassing for him... He declined.'

In a subsequent stream of tweets, she accused Knabenbauer of mentally 'abusing' her, claiming he 'gaslit' her by denying his extramarital relations with Conrad.

She said that leaving the marriage was difficult as Knabenbauer 'had absolute financial and social control over me. I have been powerless by comparison.''

Knabenbauer, who is known for his comedic video game reviews, has not responded to his estranged wife's sensational claims.

Conrad has also not issued a public statement, and has now set her Twitter account to private.

Later, O'Ferrall went further, claiming that her famous former spouse exchanged nude images with impressionable fans.

'He has been soliciting nudes from his fans for years. I was there. In the beginning, it was a joke on (blog site) Tumblr,' O'Ferrall posted.

'It was ostensibly a body-positive space for consenting adults, and I approved on that basis.... [but] he started a Snapchat, for getting nudes from fans, without telling me. I found out via a fan comment. I felt pressured to allow it even though I was uncomfortable.'
