Who Is Us Weekly's Style Icon of the Decade? - Us Weekly

From the daring, low-cut Versace dress she rocked at the 2000 Grammys to the Old Hollywood-glamour Armani Prive gown she donned to the Oscars last month, Jennifer Lopez has long been a fashion force.

That's why Us Weekly named the singer-actress, 40 (whose newest romantic comedy, The Back-Up Plan, hits theaters Friday), Style Icon of the Decade.

"It's an incredible honor!" the mom of 2-year-old twins Max and Emme tells the new Us Weekly. "When they told me, I was just like, 'Really? Oh, my god! That's so awesome.' It's just so great for me, because I really do love fashion, and I have since I was a little girl."

Lopez, along with Us' other Hot Hollywood style winners (see list below), will be feted at Us' annual Hot Hollywood bash in L.A. Thursday. (All the gossip and exclusive photos will be featured on UsMagazine.com Friday!)
