While the broadcasting watchdog hasn’t revealed exactly what viewers aren’t happy with, Sunday’s show included some of the raunchiest scenes in Big Brother’s 16-year history.
Viewers saw Marco Pierre White Jr and Laura Carter take their relationship to the next level, when during a private moment in the pod, she choked him with a belt while kissing and writhing around on the sofa.
They then retreated to the bedroom, and while bosses haven’t commented on exactly what happened, many viewers commented that it seemed as though the pair had sex.
The scenes were preceded by a warning that informed viewers they were about to be shown “risky sexual behaviour”, but this hasn’t stopped the complaints rolling in.
It may not have been the scenes of a sexual nature that inspired the complaints though, as the episode also included a meltdown from Huey and a fiery confrontation between Marco and Georgina.
Marco was also called to the diary room after showing aggression towards Ryan Ruckledge, while Saturday's show also saw conversations about drug use,
A statement from Ofcom (via Digital Spy), read: "We will assess these complaints before deciding whether to investigate or not.”
It’s not just Marco and Laura’s sexy antics that have raised eyebrows, as while viewers were under the impression that they met for the first time in the house, a photo of the duo together, taken nine weeks ago, has been discovered.
Marco’s fiancée - yes, his fiancée - has also spoken out to dispute his claim that they have an open relationship, reiterating that she has just given him a “hall pass” for the duration of the show.
