The 'Earthquake' singer admitted that she was upset by recent jibes about her weight and is trying to remain "thick-skinned".
"It is really difficult. I guess just doing this job you become used to it whether it's on the internet or in the papers, people saying things which simply aren't true about you," she told BBC Newsbeat.
"I think the internet is just a place where if you make yourself known publicly on it you're going to be open to people's opinions.
"You've just got to be quite hard-skinned about it and try not to worry if someone says you're fat or ugly or untalented - which they do."
She added: "I guess you can go online and defend yourself but it feels like you're sinking to their level and rising to their bait that way.
"So sometimes it's actually worse to respond when you read things which you know aren't true about you but you have to swallow them really."
A recent post on Little Boots's Twitter page read: "Ok getting really bored of people calling me fat online now... diet started yesterday, you don't have to rub it in."
