The 32-year-old "Blown Away" singer has "learned her lesson" and stays away from looking herself up on the Internet after previously having her day ruined by online negativity, reported Female First.
"I don't Google myself any more. Some people can be so negative. You will have 99 per cent of people being complimentary, but then you just get one meanie and it can ruin your day."
Underwood, who has a six-month-old son Isaiah with husband Mike Fisher, believes the popularity of social media makes it easy to be a "jerk" because of the aspect of anonymity.
