Britney Spears' new album is "like 'Toxic' times 10". Music producer Sean Garrett - who has worked with Beyoncé Knowles, Jennifer Lopez and Mary J. Blige - is master minding the troubled singer's comeback record and thinks it will be "exceptional". Garrett said: "I'm working with Britney."It's really coming together right now. I know she'll do exceptionally well now that she's out of rehab."The new album is like 'Toxic' times 10. It's going to be a lot of fun and it's really exciting. We did a lot of great work before her break."Britney, 25, and the producer had worked on five tracks for the new record before she entered Malibu's Promises rehab centre on February 20. After checking out of the centre, Britney seems to have tamed her wild partying. Garrett said: Britney is a superstar. She definitely knows how to handle herself, but it's tough sometimes. The pressure sometimes gets to you, but I think she has done such a great job keeping her composure under the circumstances."
