 Shetty, 31, is an award-winning Bollywood actress |
Some 200 viewers have complained that the actress is being targeted by some housemates because she is Indian.
Jade Goody, Danielle Lloyd and Jo O'Meara have ganged up on Shetty in the past few days.
Channel 4 described the situation as "girly rivalry" while Shilpa's mother said she should treat it as "a game".
Jade Goody's mother, Jackiey, repeatedly referred to Shilpa as "the Indian" while she was on the show and was unable to pronounce her name.
Over the weekend, former Miss Great Britain Danielle Lloyd and ex-S Club 7 star Jo O'Meara poked fun at Shilpa's accent.
An Ofcom spokeswoman said: "We have had approximately 200 complaints of racism.
"Quite a lot of websites have been discussing the issue and urging people to get in contact with us. We will look into each individual complaint." 
Shilpa is too good-looking for her own good 
Shilpa's mother, Sunanda Shetty, told the BBC Asian Network her daughter was tough: "I hope that she will be able to handle the situation. It is a game and there is a life beyond that.
"I mean, I understand her emotions but I really hope that she is not going to get too affected by this treatment that is being meted out to her."
Evicted housemate Carole Malone has said she believes the incidents are motivated by jealousy.
"Shilpa is too good-looking for her own good," she told the Asian Network.
"She's an incredibly powerful and beautiful woman. She is a very strong woman and can handle it. I spoke to her about it when I was in the house."
Malone added: "Shilpa feels that she represents the Indian/Asian community and doesn't want to let them or herself down by retaliating."
