Luke Bryan was on Ellen Wednesday for his final appearance on her show. He reveled that he suffered a panic attack the first time he was on the show. It was back in November 2011 when he was Ellen's special correspondent on the red carpet at the CMA Awards. It was also his first time performing on the awards show, and Luke says the pressure really got to him as a younger artist. He started having a hard time breathing in the limo on his way to the awards. "I chugged a bunch of whiskey...and then I did the red carpet. I got through it," he says with a smile. "Hey, entertainment's a grueling little business!" Luke ended his time on the show by raising a beer to Ellen - a can of his own Two Lane beer.
