Yeah, Shakira is ticklish on her sides. I posted this a long time ago; in fact, it was one of my very first postings in the celeb section -- back in about July -- but no one responded to this back then.
There is a show on Univision named "Control", a weekend music/entertainment program targeted towards hispanic teens. They showcase upcoming artists all the time; Shakira has been in it plenty of times.
About three or four years ago -- when Shakira was just becoming popular -- in a casual interview with the host, he poked her a couple of times on the side. Each time, she jumped and squealed, saying something like "Ya no!", which means "No more". Good tickling action; great reactions.
