Saldana compliments Spears

Actress Zoe Saldana says there's a reason why singer Britney Spears enjoyed more popularity than other singers, who had a better voice.

"Spears is a very beautiful human being. After I worked with her, I realised that there was a reason why she was the most popular pop artist over so many other pop artists at that time who were more talented, had better voices. And it was because of her heart, her soul," huffingtonpost.com quoted her as saying.

The two worked together in the 2002 film "Crossroads".
