Love Island's Gabby Allen will face a brutal final interrogation that sees her branded a 'useless f***ing talentless t***' and doused in water as the series draws to a close. 

The reality TV star is one of the final five battling it out to pass the course, a condensed version of SAS training, that is overseen by Billy Billingham, Rudy Reyes, Chris Oliver and Jason Fox. 

She will face the toughest challenge yet alongside Dani Dyer, Ben Cohen, Mack Horton and Emily Seebohm, in the episode which hits screens tonight (January 26). 

And in the process will be dished out a series of savage take downs from- and have water thrown in her face - while undergoing 12 hours of interrogation. 

The final task will be the five remaining recruits placed in stress positions while being forced to listen to difficult sounds on repeat, in between being questioned face to face.

During the tense scenario, Gabby, 33, won't be able to hold her tongue, and dishes out a sassy quips in response to the interrogator, smirking in his direction. 

'I could line ten women off Love Island up, you'd all look the f***ing same,' interrogator Ian Dilks begins, before pointing towards her face. 

'You've all got generic lips, you've got eye lashes like a cow, all the same... so what makes you any different to any other trollops?' 

Refusing to answer the question, Ian then shouts in her face: 'You can f***ing answer, you know.' 

'That’s fair enough, that’s your opinion,' Gabby sassily replies, before Ian continued: 'You’ve not got much else going on have you? Not using the old f***ing brain.'

But when Gabby simply gives back an 'OK', the interrogator further loses his temper, continuing: 'What do you mean OK?!' 

Watching on from outside the room, the umpire of the series comments: 'F***ing hell. Anywhere else they would have had a bloody good slap by now.' 

Grabbing Gabby by the collar, the interrogator goes on: 'F***ing talentless little t***s like you mean f*** all to me. You’re f***ing useless. F***ing smirk away.'

Reaching for a bottle of water, he then asked if Gabby wanted to have a drink, but when she replied 'no thanks, sir' - he throws the water in her face, adding: 'F***ing have one.'

Pouring out the remainder of the bottle over her head, he concludes: 'Have the f***ing rest, sort your hair out.'

Meanwhile,  England rugby legend Ben Cohen will be hit with a savage Celebrity SAS: Who Dares Wins interrogation that will see him called a 'sad old man' by the directing staff.   

The former sportsman, who is clinically deaf after suffering genetic hearing loss, was seen choking up in last night's episode as he opened up on the gruelling series. 

The World Cup winner admitted appearing on the Channel 4 series left him 'vulnerable' after it triggered 'different mindsets' to get through the challenges. 

Looking exhausted, Ben will be put through the interrogation that includes the barrage of insults, according to the Sunday Express. 

Ian tells Ben: 'I recognise your face. Didn’t you used to play rugby? Didn’t you win the World Cup? They say never meet your heroes because it’ll be disappointing. It’s quite sad really.

'You’re like an old man. So as a "husband-rugby player", what are you doing here now?'

Ben replies: 'I’ve been running across the country, sir,' and when prompted to explain why, he continues: 'I’m trying to figure that out.'

After the interrogation, Ben tells the staff that he's barely hanging on in the process, concluding: 'I am tired. The interrogation is probably one of my biggest question marks.

'It’s wearing you down and making you feel vulnerable, triggering different mindsets, thoughts and testing them – the mental challenge of it, the mental toughness of it.'

Last night, Ben was seen having a video call with 2003 World Cup winner Steve Thompson, where he struggled to control his emotions as he opened up about his time on the show.   

'It’s been really tough. It’s been soul-searching. I have had some really horrible mental battles.'

Celebrity SAS: Who Dares Wins concludes tonight at 9pm on Channel 4
