Christina Milian mixed a black bikini with a fishnet skirt when she hit the pool with a group of friends in Miami yesterday. She was clearly excited to be getting in time by the water as she took to her Twitter account during her pool stop and tweeted several photos of herself in her "little black bikini" and smoking an electronic cigarette. Later, Christina and her friends hit up the Liv nightclub in Miami. She is currently preparing for the September return of The Voice, where she serves as the show's social media correspondent. The show made headlines earlier this year when it confirmed that original judges Christina Aguilera and Cee Lo Green will be returning to the program after taking a season off.
