Maybe being absolutely everywhere for the past year has caught up with Lady Gaga, who had to cancel a concert last night due to an irregular heartbeat caused by dehydration and exhaustion. Well, if exhaustion means "being on Oprah."

It seems that Gaga showed no signs of illness when she performed live for the goddess of Chicago today. You can say lots of things about Gaga, but she doesn't seem like she would intentionally cancel her appearance to a packed amphitheater after the opening acts performed just to go on a talk show. However, it does some sort of coincidental. She rescheduled the concert for later this month, but maybe after that it's time for a nice rest. Right, Gaga?
