Mary Kate & Ashley Olsen, P. Diddy, Justin Timberlake, and ... Sylvester Stallone? The real-life '80s icon is teaming up with veteran retail executive Michael Henry and other unidentified financial backers to launch Stallone, a men's lifestyle brand under the umbrella of a larger business called Sly Inc. "Clothing is the first step to building a character," Stallone told Men'sWeek before adding that finding the right outfit - sweatsuits, camo pants, and t-shirts - was crucial to creating Rocky. But it was the Rambo franchise that led him to become "truly involved in style," when he lost a lot of weight, started buying custom clothing, and "found out I really liked this world." Fittingly, his collection is inspired by Rocky "the rebel" and Rambo "the gentleman," and will include jeans, shirts, outerwear, underwear and watches. The collection is set to launch in 2012. Shortly thereafter, Stallone and his partners hope to build up the brand with eyewear, grooming products, and athletic wear.
