A controversial game exploded into a fiery argument on Love Island: All Stars on Sunday night and the repercussions are still being felt.

Harriett Blackmore and Casey O’Gorman had an almighty spat after answering questions in the revealing To Be Honest segment, resulting in Harriett telling the season nine star to ‘shut the f*** up’.

Casey, 28, pulls friend Sammy Root, 23, to one side to discuss the flare up in Monday’s installment, and says: ‘She hasn’t even apologised…it’s so rude.’

This plants the seed for a string of further arguments between the pair, starting with Harriett telling her fellow contestant to ‘just chill out’.

She says: ‘I’m sorry for saying shut the f*** up, I didn’t mean it in that way, it’s just the way we speak to each other…just chill out.’

Casey replies: ‘No it’s not…imagine if I told you to shut the f*** up…I’d never be that rude.’

Later a conversation between Harriett and friend Luca Bish involves the pair not seeing eye-to-eye. Can things be fixed between them or has the friendship run its course? 

It’s not just Casey that Harriett is angry at, with the season 11 singleton, 24, directing her ire towards her pal Luca Bish, 25, accusing him of not defending her.

‘I feel like you don’t really have my back,’ she fumes. ‘If some people are speaking about me sometimes, you don’t look out for me the way I look out for you.’

Luca tells her: ‘I wouldn’t have to defend you if you didn’t put yourself in that situation…you shouldn’t say to someone to shut your f***ing mouth.’

The conversation continues with the pair not seeing eye-to-eye. Can things be fixed between Harriett and Luca or has the friendship run its course?

During the game, Ronnie Vint, 28, and Harriett were voted for ‘lacks a sense of humour, one partner clearly wears the trousers and most likely to get caught looking at each other’s phones’. 

While Ekin-Su Culculoglu, 30, and Curtis Pritchard, 29, were given, ‘most likely to cheat on each other’ and Casey and Gabby Allen, 33, were voted for, ‘the couple that’s in it for the clout’. 

On the same night, the islanders were left gobsmacked as three couples were revealed to be at risk at being dumped in a major twist. 

Following the intense game, the stars received a text revealing that Ekin-Su and Curtis, Harriett and Ronnie, and Gabby and Casey, had the most votes from their co-stars, making them vulnerable.

On Monday Casey, 28, pulls friend Sammy Root, 23, to one side to discuss the flare up and says: ‘She hasn’t even apologised…it’s so rude’

However in a huge plot twist, it was revealed that who will be dumped is out of the stars’ hands as the public would be voting to save their favourite couples.

The islanders were left in shock by the news with many only saying, ‘oh my god’ and holding their hands to their faces before the episode dramatically ended.

And tonight Maya Jama makes a stunning return to the villa, announcing to the islanders: ‘It’s been a minute!’

Maya asks all of the singletons to meet her at the firepit, telling them: ‘These games cause a lot of drama in here!’

The islanders laughed and replied in unison: ‘It’s never just a game in the garden!’

Maya first lets the villa know which couple received the most votes from the public and therefore are safe, before delivering the news that one couple has been dumped from the island immediately.

The eviction comes after a more pleasant start to the show which sees Ekin-Su keen to make Curtis’s birthday a day to remember.

With some help from Catherine Agbaje, 24, she makes breakfast and spells out, ‘I [Heart] U’ with an impressive array of fruit.
