The American Idol judge's manicurist gave the lowdown on her nail regimen for the show, saying J.Lo gets a fabulous mani every day she's due on set.
"[The] start of each day is when Jen will try clothes on, and then the nails come next," celeb manicurist Tom Bachik told E! Online. "Sometimes we play off the eyes or shoes, or elements from the dress. We think, what's the mood of the day?"
The duo loves playing with color and trying new shades when it comes to her nails, and that she "wears gel polish a lot."
And she never hits him with a diva 'tude either.
Tom said working with the "Hit the Floor" crooner is a blast, adding, "Everyday is like going to hang out with family with friends. It's upbeat, and we push each other to do new things."
