Big Brother is being investigated by TV watchdog Ofcom after 1,225 viewers complained about 3 separate incidents on the show and its sister programme Big Brother's Bit On The Side.
The regulatory body will now try to establish whether the broadcasting code has been breached.
The incident that has received the most complaints - 1,108- is a scene showing contestant Conor McIntyre calling Miss India UK winner Deana Uppal 'a piece of sh*t'.
In another incident, housemate Caroline Wharram left 114 viewers appalled after she described black contestant Adam Kelly as a 'ridiculous gorilla' with 'no sanitation'.
Three complaints were made when Big Brother 5's Victor Ebuwa used the phrase 'functioning retard' during an episode of Big Brother's Bit On The Side.
This is the second year in a row that the Channel 5 show has been reported to Ofcom - last year, BB breached the code by screening offensive language straight after the 9pm watershed.
A show spokesman says: 'Channel 5 is committed to complying with Ofcom's broadcasting code.
'We will help to facilitate a speedy investigation into this particular episode of Big Brother and Big Brother's Bit on the Side.'
