Lindsay Lohan's partner in a new tanning business has hit back at allegations the actress has been secretly using a rival product.The 22-year-old Mean Girls star will launch her tanning potion Sevin Nyne later this month - touting it as the secret to her glowing complexion.But sources tell the New York Daily News that Lohan has employed the tanning services of rival brand Fake Bake several times in the past few months as she prepares for the launch of her own product.The newspaper quotes a source saying, "Lindsay tans on the sly, and will have the van come to the house of her girlfriend (DJ Samantha Ronson) instead of her own for discretionary purposes."But Lohan's business partner, Kristi Kaylor, refutes the claims, insisting, "Lindsay only uses Sevin Nyne. As well as perfecting the solution with our lab and choosing the scent, Lindsay named the product, art-directed the visual components and has been involved every step of the way. Lindsay also has her own (tanning) machine and gallons of Sevin Nyne solution that she uses regularly."
