The consummate fashionista in her real life, Jennifer Lopez relished the chance to wear tons of vintage ’70s and ’80 fashion playing Pucchi, the wife of legendary salsa singer Hector Lavoe in El Cantante. At last night’s Los Angeles premiere, the glammed-up actress told PEOPLE that “I loved it. I think I had about 50 changes in the movie. Sometimes we’d do five, six changes a day because we shot the movie in only 36 or 37 days. We just had a great time putting it all together.” To see all of J. Lo’s sultry costumes (and her on-screen chemistry with husband Marc Anthony), check out the movie which opens on Friday.
