The hip-shaking bombshell is back. On the heels of 'Waka Waka,' Shakira has released the second single, 'Loca,' from her forthcoming album, 'Sale el Sol/The Sun Comes Out,' scheduled to be released on October 19. On the album cover, the sultry songstress shows her love for Silly Bandz -- silicone bands that form into shapes, including animals and words, that are normally worn as bracelets. In anticipation of her album release, Shakira shot her 'Loca' video with Dizzee Rascal last month in Barcelona, Spain, using a a handheld camera. The Colombian pop princess was in hot water after she was filmed dancing in a public fountain with locals and riding a motorcycle without a helmet, officials in Barcelona told the press last month. Hoping to capture a raw, "homemade" video, Shakira left her production team at home, so she could capture the true spirit of being 'loca' in the streets of Barcelona. "Barcelona is one of my favorite cities and has become a second home to me," said Shakira. "The video is just about having fun and being real in this amazing place with real people."
