During his time in the CBB house, Biggins had shocked viewers with his comments about being bisexual during a conversation with Mobwives star Renee Graziano. He made several comments about bisexuality, including: "The worst type, I'm afraid to say, are the bisexuals. What it is, is people not wanting to admit that they're gay? Be honest. That's what you've got to be."
Ofcom has since received complaints over Biggins' comments and a spokesperson has now confirmed, they will be investigated.
According to The Sun, a spokesperson for Ofcom had said: "We're investigating whether a contestant's comments about bisexual people were offensive and breached generally accepted standards."
Shortly after the comments were made, Biggins exit from the CBB house was confirmed. He was forced to leave at the beginning of August, after making "a number of comments" that could have offended both housemates and the wider public.
A statement said: "Big Brother has taken the decision to remove Christopher Biggins from the Celebrity Big Brother house.
"Since entering Big Brother, he has made a number of comments capable of causing great offence to housemates and the viewing public. Big Brother does not tolerate offensive language capable of causing widespread offence. Christopher Biggins has left the house."
No details about the exact comments were given at the time, but it later came to light that Biggins had made comments about the Holocaust to his fellow housemate Katie Waissel - something which he has now apologised for.
Christopher had said following his exit: "I am mortified by what's happened, really mortified... I apologised to Big Brother and Katie."
Ofcom, meanwhile, will not be investigating those particular comments as they were not aired on the show.
