Yeah, so, this happened, and those familiar with the life of former "Doogie Howser, M.D." star Neil Patrick Harris know that there is zero chance it will happen again. Heck, let's be honest. It probably wasn't even happening when it was happening. NPH once told Howard Stern that he realized he was gay when he was dating Christine in 1997 and felt no attraction to her, and Christine was likely very thankful for that interview.
