Sam Thompson has unleashed a fresh prank war on girlfriend Zara McDermott after pretending to put a hair removal strip over one of her eyebrows.

The Made In Chelsea star is notorious for playing practical jokes on his former Love Island star girlfriend, 25, but he may have gone one step too far in his latest attempt to trick her.

Sam, 30, uploaded a hilarious video to his Instagram page where he showed himself preparing the fake wax strip for his 1.5million followers.

Speaking to the camera, he addressed his fans: ‘This is either going to work or be s**t,’ before filming himself walking towards Zara, who was laying in bed.

‘I couldn’t find you the right tea, but I did find you this,’ he told the former X Factor: Celebrity star as he placed the strip over her right eyebrow.

‘What are you doing?’ Zara asked, before repeatedly exclaiming, ‘No!’ and placing a hand over her mouth.

‘Don’t panic, it’s fine,’ Sam teased as distraught Zara said: ‘Oh my God, no, you don’t actually understand what you’ve done.

‘Can I just say one thing? Things like this aren’t actually f**king funny, because this is permanent.’

Realising there are less than two weeks to go until the big day, Zara shouts, ‘For Christmas! I’m going to have no eyebrow.’

She then yelled at her other half while bursting into tears: ‘Leave the f**king room now, leave the room.’

Putting Zara out of her misery, Sam – who hosts the podcast Staying Relevant with Towie’s Pete Wicks – tells her ‘It’s a prank, it’s a prank, it’s just sellotape,’ before ripping the strip from Zara’s brow.

Falling into hysterics, Sam asks his girlfriend ‘What have you got to say?’ before lowering his tone and asking if she is OK.

In the caption of his upload, Sam joked: ‘She went through so many emotions…just remember…she started it.’

Fans soon flooded the comments section of the post, with one writing: ‘I am SO glad you didn’t use actual wax. You actually did a prank how a prank is supposed to be done.’

However, others left advice for Zara on how she could get her own back, with one telling her: ‘you have the patience of a SAINT I tell you now hair removal cream in the shampoo for even putting you through this.’

While a second added, ‘actual wax strip to the balls as revenge, Zara. I went through all those emotions with you!’
