Jennifer Lopez turned 42 Sunday, and reportedly rang in the big day the best way she could - partying carefree and solo in Miami Saturday night!

Given that she just announced her divorce, and given all the rumors of Marc Anthony cheating on her, it's nice that she was able to just let loose.

The American Idol judge has starred in more than two dozen films and released seven successful albums. Not a bad resume for the 42-year-old.

Here's hoping her 43rd year brings more success and happiness. Click to enlarge some of our favorite J. Lo pics below and wish her a happy b-day:
