Louis Vuitton’s Impulsion sunglasses ($450) are quickly becoming the go-to item when it comes to luxury eyewear. We’ve already seen Jamie Foxx as well as LL Cool J in these sunglasses, however two new celebrities have joined in on the Impulsion fun. Timbaland, Ray J, and Jamie Foxx were all spotted at the Hard Rock Hotel & Casino in Las Vegas wearing the same Louis Vuitton Impulsion sunglasses from the Spring/Summer 2010 menswear collection. We don’t know whether this was planned or just coincidence, but one thing’s for sure, these sunglasses are popular.
