'They're disgusting scum': Big Brother viewers left outraged by Marco Pierre White Jr and Laura Carter's 'porn star' antics after they appear to have SEX on air The Big Brother housemates shocked viewers with the sexual activity, with 252 complaining to Ofcom Fans claimed scenes from the Channel 5 show were 'pornographic' Marco's fiancée Kim Melville-Smith has admitted she gave him a 'hall pass' for his appearance The son of chef Marco Pierre White is reportedly appearing on the show to pay off debt Sunday's episode had 1.1m viewers - its best ratings since Tuesday's launch show Big Brother viewers were left disgusted on Sunday night when housemates Marco Pierre White Jr and Laura Carter appeared to have sex. After days of outrageous flirting and kissing, the pair seemed to take things to the next level and had sex in the bedroom. Ofcom confirmed there had been 252 complaints from viewers of the Channel 5 reality show over the weekend, which were being assessed. The raunchy scenes, screened during the 9pm highlights show, featured the son of celebrity chef Marco Pierre White and club hostess enjoying foreplay on the sofa. At one point, the 30-year-old redhead lifted up her top as Marco Jnr, 21, sucked her bare breast. Viewers watching at home took to Twitter to express their shock, with many comparing the scenes to 'porn' and declaring they made them feel 'sick'. The pair's coupling has been made even more awkward for viewers because Marco Jnr has a fiancee on the outside. When he entered the house last week, he claimed his future wife Kim Melville-Smith, 36, had given him a 'hall pass' during his time on the show. Marco Jnr and Laura shared their first kiss on Friday's episode after just a few days in the house so it didn't take him long to use his so-called pass. Following a flurry of outrage on social media on Sunday, Ofcom confirmed they had received complaints over the weekend. A spokesperson told MailOnline: 'We will assess these complaints before deciding whether to investigate or not.' A Big Brother spokesperson declined to comment when contacted by MailOnline. No doubt the risque scenes will boost Big Brother's ratings after the launch show last Tuesday received its lowest audience yet, with 1.4million tuning into the two-hour live episode, down 300,000 from previous year's show. Sunday night's episode saw a total 1.1million viewers, its best figure since Tuesday's launch. Marco and Laura appeared to take things to the next level when he claimed he wanted to 'f*** her brains' out during the boozy evening. He also made kinky suggestions as he asked Laura to 'strangle me' as he carried his belt. She replied: 'I’m not going to strangle you on TV.' Marco attempted to reassure her: 'It’s safe…whip me with it.' The 30-year-old then complied and slapped his face with the end of the belt, to his delight. Before heading to bed, the couple attempted to get some privacy in the shower, as they ran inside the cubicle whilst fellow housemate Emma Jenson brushed her teeth just metres away. Leaning into her new love interest, Laura explained: 'I want you so badly,' as they kissed each other before she exclaimed: 'You've got your microphone on!' Following a boozy session with their fellow housemates the pair also couldn't stay away from each other in the garden, with Marco ripping up the model's top as she went braless in the garden During their outdoor tryst, he also placed his hands down Laura's shorts before she whispered 'not here'. The radiant redhead, who famously claimed to have had a threesome with Justin Bieber in a London hotel last December, continued to put on a sultry display as she writhed on top of him. Later in the episode, the pair enjoyed a passionate kiss under the sheets in bed, getting incredibly hot and heavy under the covers, prompting the speculation they had gone all the way. Laura previously claimed she would be staying away from Marco as she 'feared' for her career after indulging in several steamy sessions with the engaged star, but the pair didn't hold back as they put on a steamy display. Just hours earlier, Laura had explained: 'I just don't want to be that girl,' as she reevaluated her relationship with Marco, but he insisted that and his wife-to-be Kim have an 'open kind of thing'. However, after Marco made a pact with the model to sleep together on a casual basis, he appeared to be going against his fiancee's wishes. Fashion designer Kim, 36, tweeted on Sunday: 'Fyi I said #hallpass NOT open relationship. I don't watch bb, but I heard this today. Worst thing I can't even talk to him.' She added: 'Yes guys, I'm Marco's fiancée. I just wanted to put a few facts straight, that's all... #bbuk #bbmarco. 'That's all I'm saying guys. Sorry. No questions.' Following the episode's broadcast, it appears she hasn't watched her fiance's latest antics, tweeting: 'What has happened? #bbuk #bbmarco I'm out and have no idea... I'm at a fashion event...'
