LATEST: Latin stars Shakira and Jennifer Lopez are among the celebrities to voice their support for singer Alejandro Sanz, after he cancelled his St. Valentine's Day concert in Venezuela when he discovered he was "unwelcome" in the country. Sanz was originally slated to perform in Caracas in November (07) but that show was scrapped over comments he made against Venezuelan leader Hugo Chavez. He then rescheduled the show for Thursday (14Feb08) after fans begged him to reconsider, but that gig was cancelled last week (08Feb08) following his discovery. And now Latinas like Shakira and Lopez have joined fellow entertainers like Ricky Martin and Penelope Cruz to sign an open letter protesting Venezuela's stance towards Sanz. The letter reads, "Because we believe in a Latin America where we should be free to express our opinions... we hope in our hearts that this problem is resolved."
