Cuba controversy was shocking: Beyonce

London: Pop star Beyonce Knowles admits her recent Cuba trip blacklash was quite shocking for her.

The `Crazy in Love hitmaker` and her husband Jay-Z headed to Havana to celebrate their fifth wedding anniversary last month, prompting some politicians to question whether the musicians had been given the appropriate clearance as American citizens, reported Daily Star.

"It was such a beautiful trip. I met some incredible children, visited some incredible entrepreneurs and learned so much about so many people and it (the controversy) was actually quite shocking," she said.

Jay-Z also addressed the controversy in his song `Open Letter`, in which he took aim at critics for attempting to investigate their intentions.
