The correct word is "regardless." "Irregardless" is not in my dictionary. It may have been added to some dictionaries because of it's all too common usuage. This happens in language sometimes. Sometimes the illiterate win.

Here is the entry from the American Hertiage Dictionary:

ADVERB: Nonstandard Regardless.
ETYMOLOGY: Probably blend of irrespective and regardless.
USAGE NOTE: Irregardless is a word that many mistakenly believe to be correct usage in formal style, when in fact it is used chiefly in nonstandard speech or casual writing. Coined in the United States in the early 20th century, it has met with a blizzard of condemnation for being an improper yoking of irrespective and regardless and for the logical absurdity of combining the negative ir– prefix and –less suffix in a single term. Although one might reasonably argue that it is no different from words with redundant affixes like debone and unravel, it has been considered a blunder for decades and will probably continue to be so.

Garth,
It's like feeding a troll to argue regardless/irregardless with someone who cannot correctly spell definitely.

Perhaps he was correct when he said, "Irregardless is definately a word." Now if we can find a definition (or is is defanition? or defination?) for definately...

It has been contrary to protocol to use "irregardless" in pleadings/arguments, both oral and written, before the U.S. Supreme Court. I do not know if this will continue under Chief Justice Roberts – but it would be good if the policy was continued.
