NASCAR driver Kasey Kahne has sparked a real rampage on Twitter over breastfeeding in public, after he said he was disgusted to see a mom’s breast as she was feeding her son in a supermarket.

Kasey Kahne, 31, said he first thought he was imagining things, but once he realized the mother was indeed nursing, he began tweeting his horror.

“Just walking through supermarket. See a mom breast feeding little kid,” the bachelor tweeted.

“Took second look because obviously I was seeing things I wasn’t!”

Upon second look, Kasey Kahne described the woman’s breastfeeding in detail.

“One boob put away one boob hanging!” Kasey Kahne tweeted, with the hashtag “#nasty “ following the post.

The NASCAR driver was apparently so repulsed that he then wrote: “I don’t feel like shopping or eating anymore.”

Later, a woman named Deana P. tweeted to him that she disagreed breastfeeding was “nasty” and that he was “kind of a douchebag”.

“I hope someday you have a kid and someone tells your wife that feeding your child looks nasty,” Deana P. wrote.

“Stay classy a**hole.”

Kasey Kahne, who currently stars in an Allstate ad campaign that centres around his appeal among women, responded by calling her a “dumb b***h”.

However, late last night, the racer apologized via his Facebook page, writing: “It was in no way my intention to offend any mother who chooses to breastfeed her child, or, for that matter, anyone who supports breast feeding children.

“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.”

Kasey Kahne also apologized to Deana P., saying his remarks were “out of line”.

Deana P., whose Twitter page indicates she’s a mother of three from Minnesota, wrote an apology of her own, saying her comments to the racer were also “knee-jerk and out of line”.

Kasey Kahne’s NASCAR sponsor Great Clips also released a statement, which read: “Our apologies for this. Please know that response was uncalled for & does not reflect our organization.”

Kasey Kahne’s very public qualms came amid another breast-feeding controversy, which resulted in hundreds of mothers in 35 states staging a nurse-in at their nearby Target stores after a Texas mother was told last month that she could not breastfeed in public.

Michelle Hickman, a mother of four, was trying to do some Christmas shopping last month when Target employees asked her to relocate to a more private location, such as a family fitting room.

Humiliated by the incident, Michelle Hickman used Facebook to organize the massive “nurse-in”.

Kasey Kahne, who has 12 NASCAR wins to his credit, does a great deal of charity work through his “Kasey Kahne Foundation”, which benefits chronically ill kids and their families.

In 2007, however, Kasey Kahne found himself on the wrong side of the law.

In November of that year, he was charged was charged with assault for pushing an elderly security guard at the Homestead-Miami Speedway in Florida.

The misdemeanor charges were later dropped after Kasey Kahne completed 50 hours of community service.

Kasey Kahne was also slapped with a civil suit by the security guard, who claimed he suffered a severe back injury as a result of the incident, but that suit was settled in 2009.
