The glamour model and actress said that she is never usually noticed when she visits "glamorous destinations" and admitted that she finds it difficult dealing with people speaking to her on the street.
"When I'm in nice shops or glamorous destinations, no-one ever seems to notice me," she told Nuts magazine. "It's only when I'm in Pizza Hut or Superdrug or something that people come up to me.
"When I'm walking past, they tend to shout 'Gemma!' but I'm not sure what I'm supposed to do. If I stop and say hello, the blokes tend to just giggle but if I walk past them, they might think I'm stuck up. I'm definitely not that!"
Meanwhile, Atkinson also revealed that she recently made a pricing error while house-hunting in London. However, the former Hollyoaks star was so embarrassed by her mistake that she ended up taking the rental property anyway.
"Being in London has been a shock to the system because of the prices," she said. "I went to look at a flat to rent and one came up at what looked like a decent price, so I told the estate agent that I'd have it.
"The only problem was that what I thought was a monthly rent was in fact the weekly price. I was so embarrassed that I just ended up moving in anyway."
