Liv Tyler is back in the modeling game.

The model-turned-actress-turned-model again? is set to star in the Spring and Fall 2010 ad campaigns for denim brand G-Star as its "Brand Ambassador," helping the company with its U.S. expansion.

"Liv is a great fit for the brand because she exudes the perfect level of sensuality, a characteristic very important to G-Star," the company said in a statement. "She's a strong, beautiful and independent woman with an impeccable feeling for style."

The Dutch company is looking to grow from 12 stores to 50 stores in 20 major metropolitan areas within the U.S. by sometime in 2015.

And though the jeanswear maker has been seen as a fashion company and has staged major fashion shows during New York Fashion Weeks, it really wants to refocus as a denim company.

"We're a denim brand that happened to show at New York Fashion Week because we believe it's a platform into America," explained Shubhankar Ray, G-Star's global brand director, to WWD.

The brand is set to show on Tuesday, Feb. 16 at Manhattan's Hammerstein Ballroom during New York Fashion Week.

Tyler, a statuesque stunner and daughter of Aerosmith frontman Steve Tyler, has been operating under the radar for the past few years. She has a three-year-old son Milo with her ex-husband, Spacehog singer Royston Langdon.
