J. Lo is rarely out of the spotlight for long. Most recently she's been in the news for signing on as an American Idol judge, teaming with Pitbull on the hit club anthem "On the Floor," and now a high-profile split from husband Marc Anthony.

And the triple-threat's style choices are similarly prone to attracting attention. In honor of Jenny from the Block's 42nd birthday today, we took a look back at her ensembles throughout the years, starting with the era of her star-making turn as Selena.

Jen's always had an affinity for metallics, animal prints, thigh-high boots and formfitting looks that flaunt her famously curvy physique-but she can also rock a decadent designer gown when the event calls for it.

Which of J. Lo's looks is your favorite?
