Jennifer Lopez continues to prove each week that she is only getting hotter with age, and last night was clearly no exception. The star showed off her curves (a result of her continuous hard work with fitness expert Tracy Anderson) on American Idol with a nude leather bustier dress by House of CB that fit like a glove. She paired the dress with sexy Christian Louboutin nude heels.

As for her bombshell hair and makeup? "Tonight was all about going back a few decades so we went for a '90s supermodel look," said makeup artist Mary Phillips. "We did a really dark brown smoky eye and a deep chocolate lip liner with a dark nude lipstick to compliment the dress." The result? Pretty jaw dropping, if you ask us.

Stay tuned for more looks from J. Lo as American Idol continues all season long.
