Nascar driver Kasey Kahne was apparently grocery shopping when he saw a woman breast feeding her baby, prompting him to send out a tweet saying Just walking through supermarket. See a mom breast feeding little kid. Took second look because I was obviously seeing things. I wasn't! He then sent out another one saying I don't feel like shopping anymore or eating.

One follower named Deana P took offense to this, saying to Kahne I hope someday you have a kid and someone tells your wife that feeding your child looks nasty. From there, things got heated, with both sides exchanging heated, curse-laden tweets, all of which were later deleted.

Kasey Kahne later took to his Facebook page to apologize, saying I understand that my comments regarding breastfeeding posted on Twitter were offensive to some people, he wrote. For that, I apologize. It was in no way my intention to offend any mother who chooses to breastfeed her child, or, for that matter, anyone who supports breastfeeding children. I want to make that clear.

In all honestly, I was surprised by what I saw in a grocery store. I shared that reaction with my fans on Twitter. It obviously wasn't the correct approach, and, after reading your feedback, I now have a better understanding of why my posts upset some of you.

My comments were not directed at the mother's right to breastfeed. They were just a reaction to the location of that choice, and the fashion in which it was executed on that occasion.

I respect the mother's right to feed her child whenever and wherever she pleases.

Kasey Kahne has been racing in NASCAR since 2005, and has 102 top 10 places in 176 races. He finished in 14th place overall last season.
