Britney Spears' cousin and former assistant ALLI SIMS is hoping to launch her own pop career with a TOXIC team-up. Sims reveals there are plans afoot to bring the relatives together on record - once troubled Spears' current problems are a thing of the past. Sims tells Us Weekly magazine, "We will definitely collaborate on something. "I think we are kind of both open to anything. We are really good friends, we are really close, and we really love working on stuff together." Meanwhile, Sims insists her famous cousin is doing well after she was hospitalised twice in a bid to treat her bipolar disorder. The pop star wannabe adds, "She is doing well. Everybody just keeps supporting her... because everyone kind of goes through weird little patches. "I wish people would give her a break and lay off her."
