Justin Timberlake has denied rumours that he volition duet with Britney Spears on her new album.
Tabloid reports suggested yesterday that Timberlake will guest on the popstar's follow-up to 2007's Blackout LP.
However, a representative for the 'SexyBack' singer insisted that he "is non scheduled to be in the recording studio with Britney".
Timberlake and Spears dated between 1998 and 2002.
Spears's new album is expected to be released early next twelvemonth.

Study Of Hair Dynamics May Lead To Better Hair-Care Products
�From kinky perms to over-bleached waves, "bad hair days" could soon go a less frequent occurrence. Chemists report the number 1 detailed microscopic analysis of what happens to individual hair fibers when they interact with each other, an go on in noesis key to the development of improved shampoos, conditioners, and other products for repairing damaged hair, the researchers say. They presented the study at the American Chemical Society's 236th National Meeting.
Embracing that proverb, "Personal care begins with hair," consumers now drop almost $60 billion yearly on fuzz care products, one of the personal care industry's largest market segments. Despite the increasing availability of new hair care products within the past century, many products are inadequate for tackling today's strict hair treatments, the researchers say.
"Given all the unexampled hair treatments out on that point, there's a growing need to make hair feel more natural, especially for women," says study coauthor Eva Max, a doctorial student in chemistry at the University of Bayreuth in Germany. She notes, however, that researchers motionless are scrambling to put hair upkeep on a firm scientific basis. The research involves "haptics," the science of touch - how the subjective perception of match connects to objective aerofoil properties of hair and other materials
"For the first time, we present an experimental setup that allows measuring the subtle forces, both physical and chemical, that come up when single hairs slide past each other or are pressed against each other," Max says. "The findings will help provide clearer strategies for optimizing hair care products."
Max points out that conventional methods for testing the effectivity of tomentum care products involve measurement the forces required to comb hair under standardized laboratory conditions. Test volunteers are also asked to assess whisker feel, but this coming is largely subjective. A more scientific way to study hair conditioning is needed, the researchers say.
In the raw study, the researchers invented a unique technology for analyzing hair that involves mounting individual hair fibers on a cantilever tip of an atomic force microscope and measuring their interactions as they tint each former. "The scheme will reserve scientists to explore how different haircloth care products affect hair-to-hair interactions so that these products can be optimized in a more taxonomic fashion," Max says.
The researchers used this new proficiency to examine hair samples collected from volunteers. The samples, which were antecedently bleached, ranged from clean blond to dark blond in color.
The researchers constitute that pilus feels uncut and difficult to comb for 2 main reasons. On the one hand, mechanical impairment to a hair's surface, or cuticle, creates scabrous projections that jut out at perpendicular angles to other hair fibers. When hair fibers slide past tense each other, these scales create more friction than smooth hairs, causing a rough feel and making hair more difficult to comb. To soften hair, conditioners moldiness contain active agents to smooth-out these scales so that they produce less friction, the researchers say.
On the other hand, chemical changes occur when whisker fibers interact. Negative charges build up on the surface of hair that causes repulsive force between single hairs. This repulsion causes friction and makes whisker rough and difficult to comb. To solve the problem, positively charged polymers that neutralize the negatively charged surfaces are included in conditioner formula to leave a silken feel to hair.
But finding the correct formula for repairing damaged hair is no easy task, notes Claudia Wood, Ph.D., a senior scientist at BASF in Bayreuth, Germany. In addition to hair interactions, many other external factors, such as humidity, water content of hair, and hair stickiness, all regard hair timbre, Wood says.
The key to repairing these processes is to find the right-hand ratio of beneficial components in a conditioner or shampoo that optimize hair feel, Max and colleagues say. This new method will allow developers of hair care products to achieve this goal more easily, giving consumers a more honest product, the researchers pronounce. Their study was funded by BASF Care Chemicals Division.
