The Spanish pop star kissed a young girl at the Jingle Ball concert in Boston last week, and then smooched another girl at the Y100 Jingle Ball concert in Florida the next day.
Speaking to Boston radio station Kiss108 shortly after the shows, Iglesias explained why he likes to smooch his fans.
He said: 'I just get excited when I go on stage. I don't do it all the time. I've got to be in a good mood, and I was in a good mood. There was no tongue.'
One lucky fan, Cheryl Lavoie, 41, who was kissed by Iglesias at the Jingle Ball show, told People Magazine: 'It was the best night of my life. I did not expect whatsoever to be pulled up on stage… It was priceless.'
